PMT Modules - Hamamatsu Photonics

People are said to get more than seventy percent of
their information about our world from their eyes.
However, there are vast sums of information and
unknown possibilities hidden within light not visible
to the naked eye. This kind of light includes
ultraviolet, infrared, X-ray and ultra-low level light
impossible for human eyes to detect.
Since its founding Hamamatsu Photonics has for
some 55 years been investigating not only light
seen by the human eye but also light that far
exceeds this level. Hamamatsu Photonics has
marketed dozens of products and committed itself
to pioneering work in yet unexplored areas in many
fields including industrial and academic research.
The photomultiplier tube, one typical product from
Hamamatsu Photonics is a photodetector offering
exceedingly high sensitivity and high-speed
response. Hamamatsu has also developed
photomultiplier tube modules to make the
photomultiplier tube with its amazing history of
results, even easier to use in wider applications.
This pamphlet serves as your introduction to the
photomultiplier tube modules.
Hamamatsu Photonics will continue to deliver
innovative breakthroughs in a diverse range of
fields, always striving to make human life fuller and
richer by "researching the many ways to use light".

Spectral Response
The quantum efficiency of the PMT module is compared in the following graphs. Quantum efficiency is the
conversion ratio of photoelectrons per photon and is a very important factor that determines the S/N characteristic. It is essential to select a PMT module having high quantum efficiency on the wavelengths of
light to be measured. To obtain a lower detection limit with a good S/N ratio in low-light-level measurement, the dark current and dark count must also be considered as well as the quantum efficiency.
Spectral response characteristics example of PMT modules sensitive to UV through visible light are shown
in the graphs below.

Application Examples
Advances in laser technology and high performance computers are allowing dramatic progress in research that studies
the behavior of single molecules. Fluorescence-correlation
spectroscopy is one technique for measuring single molecules. The principle of fluorescence-correlation spectroscopy
was conceived in the 1970s, but it wasn't until the 1990s that
the proper equipment was around to use it. The equipment
structure is largely the same as the confocal laser microscope
but there is no Galvano mirror, and only small area of solution
is observed. The movement of the fluorescent molecules entering and leaving the area subject to observation and the fluorescent intensity are measured by auto correlation algorithm.

OZONE LAYER
Laser Radar
LASER BEAM
One use of laser radar (often called "LIDAR") is making atmospheric measurements. A laser beam is emitted into the atmosphere and the light scattered by the "atmospheric molecules" and "suspended elements" then detected. The scattered light is absorbed by "trace gases" during its return and
is therefore extremely faint. These "trace gases, and the distribution and concentration of suspended elements" can be
analyzed by measuring this faint light. Lidar is actually used in
measurements of aerosol and ozone concentrations, CO2,
SO2 and NOx concentrations, wind velocity and also the extent of visibility.
Hygiene Monitor
The hygiene monitor is also called an ATP analyzer. This device extracts the ATP held in bacteria and cells and makes
measurements by causing a reaction with the luminous reagent in the ATP using the firefly's light emission principle.
This hygiene monitor is used for making purity checks at restaurants and factories producing foods, etc. In the test, the
surface of the object for inspection is wiped with a cotton
swab and the extent of dirt or contamination immediately
found just by inserting the swab in the sanitary monitor. A
great feature of the hygiene monitor is that the photon counting method allows highly sensitive measurements using just
an extremely small amount of sample material.

Application Examples
UV/VISIBLE
LIGHT
IR LIGHT
Multi-Photon Microscope
In this method, fluorescent molecules can be excited with
near infrared light by letting the molecules absorb two photons
almost simultaneously, and the resulting visible to UV fluorescence is observed. The cross sectional area absorbing the
two photons is extremely small, so nearly all the fluorescence
must be detected as a signal at any position from the focal
point. Other advantages are that nearly twice the wavelength
is used compared to excitation by one photon. This not only
means that unwanted effects from scattering and background
noise inside the sample due to excitation light are drastically
reduced but also that damage to cells from UV light is minimized.

TRANSMITTED LIGHT
X-ray Image Readout
Devices used to read X-ray images consist of a method using
a brightness storage phosphor plate and a method for directly
reading X-ray film. The brightness storage phosphor plate can
temporarily store the X-ray information that was detected. The
stored information on the plate is scanned by a laser beam
and then extracted by measuring the fluorescent intensity with
PMT modules. The X-ray film is also scanned by a laser beam
in the same way and the transmitted light is detected as an
electrical signal, which is then converted into a digital signal.
These devices can show the X-ray image on a CRT monitor,
store and file the image on a disk, or send the image data
over a telephone line.
DNA Chip Reader
A DNA chip reader is used to analyze colossal amounts of genetic information. The DNA chip is a substrate on which a
large amount of DNA is arrayed usually by a method using
semiconductor lithographic technology, or a method dispensing the DNA onto a slide glass using a high-precision robot.
On the DNA chip, hybridization is performed on the DNA labeled by a fluorescent dye. The DNA chip is then scanned by
laser beam and by measuring the fluorescent intensity of the
hybridized DNA spot, the genetic information is acquired from
among the targeted DNA.
(Hybridization is process to link 2 chains of DNA each having
a complementary base.)

Application Examples
Portable Survey Meters
Portable radiation measurement devices or survey meters are
essential for detecting radioactive substances for public safety
in customs inspections, nuclear power plants, and hospitals,
etc. Among various radiation measurement devices, the most
sensitive type uses a combination of photomultiplier tube and
scintillator and offers sensitivity ranging from several ten to
hundreds of times higher than Geiger-Müller counters (GM
counters). Photomultiplier tubes used in this application must
be compact, rugged, and easily coupled to scintillators, and
also have low power consumption.
Flowcytometers
In a flowcytometers, cells labeled with fluorescent material
flow in a solution along a flow cell while moving at a certain interval. A laser beam is then irradiated onto the cells and the
scattered light from the cells and fluorescence from the fluorescent material are measured by a photomultiplier tube. Various kinds of information are acquired from the scattered and
fluorescence such as cell surface antigens, cell periods, number of cells, immunity functions and reticulocytes, and the
cells can also be separated from each other. Rapid advances
are recently being made in irradiation by multiple lasers, 6channel color analysis, high-speed operation, and compact
flow systems.

Application Examples
Time-correlated Single Photon Counting
Time-correlated single photon counting is used to measure lowlevel light emitted from a sample when excited with a pulsed laser,
based on the theory that a histogram obtained by repeatedly
measuring the single photon many times at a slightly delayed timing represents a waveform of the emitted light. Electrical signals
produced by a laser driver are slightly delayed and used as trigger
signals while the PMT module detects the light emission from a
sample. The PMT module output pulse signals are then input to a
time-to-amplitude converter (TAC) that produces an electrical
pulse in proportion to the time difference between a light detection
signal and a trigger signal. A multichannel analyzer (MCA) creates
a frequency distribution of the output signals from the TAC, to obtain a waveform of the light emission of the sample.

Mass Spectroscopy
Mass spectroscopy is an essential measurement technique to
analyze samples in various fields such as medicine, pharmacy and environment monitoring. Samples are ionized by vaporization under a high vacuum pressure. The generated ions
are accelerated by strong electric fields and sent to a mass
analyzer with a strong magnetic field where the ions are separated according to the ratio (m/e) of mass (m) to electron
charge (e). Ions with larger molecular weight are detected
with a PMT module in conjunction with a scintillator.

Metal Package PMT
Photosensor Modules H10720/H10721 Series
The H10720 and H10721 series are photosensor modules containing a metal package PMT and a high-voltage power supply circuit. The built-in PMT uses a metallic
package with the same diameter as a TO-8 metal package used for semiconductor
photodetectors. Despite the small size nearly equal to photodiodes, this PMT delivers high gain, wide dynamic range, and high-speed response. Four types of photocathodes are available, including a super bialkali photocathode that has higher sensitivity than conventional bialkali photocathodes, an ultra bialkali photocathode that
offers even higher sensitivity, a multialkali photocathode with sensitivity extending
to the near infrared region, and a red sensitivity enhanced multialkali photocathode. Hamamatsu also provides "P" type with low dark count selected for photon
counting measurement.
The H10720 series are lead pin output type, while the H10721 are flexible cable
output type.

Metal Package PMT with Cooler
Photosensor Modules H7422 Series
The H7422 series are photosensor modules with an internal high-voltage power
supply circuit and a cooler installed to the metal package photomultiplier tube. Efficient cooling was achieved by placing the cooler near the photomultiplier tube to
reduce thermal noise emitted from the photocathode and a high S/N ratio can be
obtained even at extremely low light levels.
The H7422-40 has high sensitivity in the 300 nm to 720 nm wavelengths. The
H7422-50 is sensitive along a wide spectral range from 380 nm to 890 nm. The
photomultiplier tube is maintained at a constant temperature by monitoring the
output from a thermistor installed near the photomultiplier and then regulating the
current to the thermoelectric cooler.

In order to protect the PMT module from being damaged by
excessive light, the H7422-40/50 has a protective function
circuit. The circuit automatically turns off high voltage if the
output current exceeds the preset current limit (approx. 10
µA). This protection circuit works whenever the preset current limit is exceeded, even for a short moment. An example of this function could be in applications such as laser
scanning microscopes where the output current may momentarily exceed the preset current limit. This will trigger
the protection circuit and interrupt measurement. In such
applications, if the average output current is lower than the
PMT module maximum rating (2 µA), we can change the
current limit in the protection circuit up to approximately 50
µA. This means that PMT module operation continues without turning off high voltage even if a momentary high output
occurs. Users can choose this option when ordering.

The A7413 mount adapter is used when a C-mount lens protruding 4 mm or more from the flange-back must be installed
onto the H7422.
● Power Supply Unit with Temperature Control C8137-02
The C8137-02 is a power supply unit with a temperature control function. Just connecting to an AC source of 100 V to 240
V generates the output voltages for the thermoelectric cooler
and the A7423 fan, needed for operating the H7422. The photomultiplier tube temperature can be maintained to 0 °C by
monitoring the thermistor and regulating the output current for
the thermoelectric cooler. Control voltage can be varied by a
knob on the front panel.

Compact Side-on PMT
Photosensor Modules H9305 Series
The H9305 series photosensor modules contain a high-voltage power supply
circuit and a 13-mm (1/2") diameter side-on photomultiplier tube in a compact
aluminum housing. The 13-mm (1/2") side-on photomultiplier tube has a
reflection mode photocathode that delivers high quantum efficiency at
wavelengths above 600 nm, an adequate gain of up to 107 and fast time
response. High S/N ratio can be obtained even when measuring extremely
low level light at high speeds.
The H9305 series uses a Cockcroft-Walton circuit with low power
consumption. Flexible cables are used for easy installation in equipment.

Compact Head-on PMT
Photosensor Modules H7826 Series
The H7826 series photosensor modules consist of a 19-mm (3/4") diameter
head-on photomultiplier tube and a high-voltage power supply circuit. The
length of the photomultiplier tube used here is short compared to other photomultiplier tubes of the same diameter, making it compact even though it has a
large light input diameter of 15 mm. The H7826 series also has excellent resistance to vibration and shock compared to other photomultiplier tubes,
making it ideal for use in portable equipment.

Metal package PMT
Photosensor Modules H10722 Series
The H10722 series is a photosensor module containing a metal package PMT, a
low-power consumption high-voltage power supply circuit, and a low-noise
amplifier. The amplifier converts the PMT current output to a voltage output so that
the signal can be easily processed. Also, the amplifier is connected close to the
PMT anode output pin in order to make the signal less affected by external noise.
Four types of photocathodes are available, including a super bialkali
photocathode that has higher sensitivity than conventional bialkali photocathodes,
an ultra bialkali photocathode that offers even higher sensitivity, a multialkali
photocathode with sensitivity extending to the near infrared region, and a red
sensitivity enhanced multialkali photocathode.

Metal Package PMT with Gate Function
Photosensor Modules H11526 Series
The H11526 series is a photosensor module that allows gate operation. The
combination of built-in metal package PMT and gate circuit makes this module compact yet still provides excellent characteristics: 100 ns minimum gate
width, 10 kHz repetition rate. This module also contains a high-voltage power
supply so that PMT gain can be varied by simply adjusting the control voltage. The internal protection monitor issues an error signal if high-intensity
light enters the module.

Metal package PMT
Photon Counting Head H10682 Series
The H10682 series is a photon counting head device consisting of a metal
package photomultiplier tube, along with a high speed photon counting circuit
and a high-voltage power supply circuit. The high voltage supply for photomultiplier tube and the discrimination level are preset to optimum values, allowing
photon counting measurement by just connecting a +5 V supply.
The H10682-110 has the super bialkali (SBA) photocathode and the
H10682-210 has the ultra bialkali (UBA) photocathode, so they have higher
sensitivity than conventional photon counting heads.
The H10682 series has also over light detection function to output a signal at
the state that an output count falls by excessive incident light. By this signal,
measurement data can be judged that it is normal or not.

Metal package PMT with Cooler
Photon Counting Head H7421 Series
The H7421 series is a photon counting head device containing a metal package photomultiplier tube having a GaAsP/GaAs photocathode and a thermoelectric cooler. The thermoelectric cooler reduces thermal noise generated
from the photocathode which also offers a high quantum efficiency, allowing
measurement to be made with a good S/N ratio even at very low light levels.
The H7421-40 has high sensitivity on wavelength from 300 nm to 720 nm.
The H7421-50 is sensitive over a wide spectral range from 380 nm to 890 nm.
The photomultiplier tube is maintained at a constant temperature by monitoring the output from a thermistor installed near the photomultiplier tube and
regulating the current to the thermoelectric cooler.

The temperature of the H7421 outer case rises due to the
thermoelectric cooler housed in the case. The A7423 heatsink
efficiently radiates away this heat to prevent a temperature
rise in the H7421. The A7423 can be easily installed onto the
H7421 with four M3 screws. Apply a coat of heat conductive
grease onto the joint surface shared by the H7421 and

Photon Counting Head H8259 Series
The H8259 series is a photon counting head device containing a 28-mm (11/8") diameter side-on photomultiplier tube, high-speed photon counting circuit,
and a high-voltage power supply circuit. The photomultiplier tube sensitive in
the near IR region usually has a large dark count due to thermal noise but high
S/N measurements can be obtained since a low-noise photomultiplier tube is
selected. The high voltage supply for photomultiplier tube and the discrimination
level are preset to optimum values, allowing photon counting measurement by
just connecting a +5 V supply.
An electronic gate circuit (shutter circuit) is also included to eliminate extraneous light such as excitation light from the measurement.

Compact Head-on PMT
Photon Counting Head H7828 Series
The H7828 series is a photon counting head device containing a 19-mm (3/4")
diameter head-on photomultiplier tube, a high-speed photon counting circuit,
and a high-voltage power supply circuit. The high voltage supply for photomultiplier tube and the discrimination level are preset to optimum values, allowing
photon counting measurement by just connecting a +5 V supply. Despite its
compact size, the effective photosensitive area is as large as 15 mm in diameter, so the incident light can be collected very efficiently. Compared to other
PMT modules, the H7828 series has higher resistance to vibration and shock,
making them suitable for portable or mobile measurement equipment.

are preset to optimum values so that photon counting can be performed just
by connecting a +5 V supply and a pulse counter.
The H7360-01 is of low noise, the H7360-02 has enhanced detection efficiency
in the visible range, and the H7360-03 covers sensitivity from the visible to
near infrared.
A mount flange (E6264) is provided as an option for easy installation to

Counting Board M9003-01
The M9003-01 counting board is a PCI bus add-in board counter that functions as a
photon counter when used along with a photon counting head. (See P.11)
The counter section of the M9003-01 has two counter circuits (double counter method) capable of counting the input signal pulses without any dead time. The counter
operates in either gate counter mode or in reciprocal counter mode. Gate counter
mode counts the input signal pulses only during each gate time produced by the internal oscillator. (Minimum gate time during gate counter mode is 50 ns.) Reciprocal
counter mode counts the number of internal clock pulses generated between input
signal pulses.
The M9003-01 does not have its own memory so it sends measurement data directly
to the PC's main memory by DMA (direct memory access) transfer. This enables
measurement of up to 64 Mbytes. External trigger signals can also be inserted into the count data as timing information.
Counting can also be performed for a predetermined number of gates starting from the input of an external trigger signal (only during gate counter mode). This allows counting periodic light emission phenomena by integrating their signals after DMA transfer.
Anyone can easily make the initial settings since the M9003-01 is PnP (plug and play) compatible. You can start making measurements right away after the M9003-01 is unpacked, by just using the sample software that comes supplied with the M9003-01.

Technical Guide
General Characteristics
Photocathode radiant sensitivity and quantum efficiency
Gain
Radiant sensitivity is the photoelectric current generated from
the photocathode when struck by light at a given wavelength,
divided by the incident radiant power, and expressed in A/W
(amperes per watt). Quantum efficiency (QE) is the number of
photoelectrons emitted from the photocathode divided by the
number of incident photons and is usually expressed as a
percent. Cathode radiant sensitivity is one factor in
determining signal-to-noise (S/N) characteristics and
detection limit of measurement systems, and is used to
calculate signal-to-noise ratio (S/N ratio) and noise equivalent
power (NEP) representing a lower detection limit.
Measurement of radiant sensitivity requires a sophisticated
system using a spectrophotometer and also takes a lot of
time. Because of this, we only attach spectral response data
showing radiant sensitivity to the photomultiplier tube when
specially requested by the customer and we charge for this
service. Cathode radiant sensitivity cannot be measured once
the photomultiplier tube is assembled as a module. If radiant
sensitivity data is necessary, please request it when placing
an order.
Gain of PMT modules listed in this catalog is the ratio of
anode output current to cathode output current, measured at
specified values of control voltage. Gain depends directly on
the high voltage applied to the photomultiplier tube, which is
adjusted by a control voltage. The gain versus voltage curves
are usually plotted on a logarithmic graph and appear as
straight lines with the same slope for the same type of
photomultiplier tube. This means that the gain of a
photomultiplier tube can be easily found by moving in parallel
with the typical gain curve.
Luminous sensitivity
Cathode luminous sensitivity is the photoelectric current
generated from the photocathode when a photomultiplier tube
receives light flux from a tungsten filament lamp operated at a
distribution temperature of 2856 K. Anode luminous sensitivity
is the anode output current per incident light flux on the
photocathode of a photomultiplier tube when a specific high
voltage is applied. The light flux is lowered to an appropriate
level by using a neutral density filter.
Luminous sensitivity data is measured and listed in the test
sheet prior to shipment except for some types of PMT
modules. Luminous sensitivity is particularly useful when
comparing PMT modules having a similar spectral response
range.
Blue sensitivity index and red/white ratio
Although different from absolute spectral response
characteristics, the blue sensitivity index and the red/white
ratio are often used for simple comparison of photomultiplier
tube spectral response.
Blue sensitivity index is the photoelectric current generated
from the photocathode when a blue filter is interposed in the
same measurement system as used to measure cathode
luminous sensitivity. Blue sensitivity index is an essential
parameter in scintillation counting because the NaI(Tl)
scintillators frequently used in scintillation counting, produce
light emissions close to the blue spectrum when transmitted
through a blue filter. Blue sensitivity index is not represented
in lumens because the light flux once transmitted through a
blue filter cannot be expressed in lumens.
Red/white ratio is used for comparing the sensitivity of
photomultiplier tubes having a spectral response extending to
the near infrared region. Like blue sensitivity index, the
red/white ratio is also measured with the measurement
system used for cathode luminous sensitivity, but a red to
infrared filter is interposed. Red/white ratio is defined as the
ratio of the cathode sensitivity measured with a red to infrared
filter, to the cathode luminous sensitivity when measured
without a filter.
72
Dark current
A small amount of output current appears from a PMT module
even when operated in a completely darkness. This output
current is called "dark current". Dark current varies with the
control voltage in proportion to the change in gain. However,
the slope of the dark current versus the voltage curve
becomes less and less steep as the control voltage is
decreased. This dark current at a low control voltage is mainly
comprised of leakage current generated on the glass stem
and lead pins or the surface of the circuit boards. When a
PMT module is operated at a normal high voltage, most of
dark current originates from thermionic emissions, especially
those from the photocathode. Cooling the module is therefore
very effective in reducing the dark current. Hamamatsu PMT
modules are designed to exhibit low dark current when used
within the specified operating temperature range. However, in
applications where dark current is a critical factor, using a
PMT module with a built-in cooler is recommended.
Spatial uniformity
When a spot light strikes the photocathode of a
photomultiplier tube, the photoelectric sensitivity may vary
depending on the photocathode position. This variation in
sensitivity is called "spatial uniformity". Spatial uniformity is
caused by the irregular sensitivity of the photocathode itself
and also by a non-uniform loss of electrons while focused and
multiplied by the dynodes after being emitted from different
positions on photocathode. Spatial uniformity also depends
on the light wavelength. In general, head-on photomultiplier
tubes provide better spatial uniformity than side-on tubes. To
reduce the adverse effects of spatial uniformity on
measurement, the input light must be made to illuminate a
wider area on the photocathode or a diffuser plate must be
placed in front of the photocathode.
Temperature characteristics
The sensitivity and dark current (dark count) of
photomultiplier tubes change with the ambient temperature.
The rate of this change (temperature coefficient) depends on
the light wavelength. As the ambient temperature decreases,
the sensitivity increases in the ultraviolet to visible region
while it tends to decrease in the longer wavelength region. As
temperature decreases, dark current also decreases because
the thermionic emission of electrons is reduced.
Technical Guide
Drift and life characteristics
Cockcroft-Walton circuit
While operating a photomultiplier tube continuously over a
long period, the anode output current may vary slightly over
time, even though the operating conditions have been kept
constant. In this kind of anode current behavior, the stability
over a short operating time is called the drift characteristic,
while the stability over an extended period of time is called the
life characteristic. Both drift and life characteristics differ
according to the type of photomultiplier tubes and the
magnitude of anode current drawn from the photomultiplier
tube. When stability is of prime importance, operating the tube
at an average anode current of 1 µA or less is recommended.
The Cockcroft-Walton circuit is a voltage booster circuit with
an array of series-connected diodes, and with capacitors
connected at each of the alternate connection points. When
a reference voltage is applied to this circuit, voltage
potentials boosted 1 time, 2 times, 3 times ... (multiplied by
integers) are applied to the dynodes of the photomultiplier
tube. This circuit delivers good linearity in both DC and
pulsed currents while maintaining low power consumption,
and allows designing a compact circuit, but the settling time
becomes temporarily long.
Time response characteristics
The time response characteristics of photomultiplier tubes are
very important when measuring high-speed signals. Time
response characteristics are usually evaluated in terms of
electron transit time, rise time and electron transit time spread
(T.T.S.). These characteristics differ depending on the type of
photomultiplier tube contained in the PMT module and must
be carefully selected to meet the application. In addition to the
time response characteristics of photomultiplier tubes, the
signal load conditions have effects on PMT module response
speeds, particularly on the current-output PMT modules. As
the load resistance is made larger, the response speeds of
the current-output PMT modules reduce.
Active type divider circuit combined
with Cockcroft-Walton circuit
This circuit consists of a Cockcroft-Walton circuit that
generates a voltage applied to the entire photomultiplier tube
and an active type divider circuit that applies a voltage to
each dynode. In the active type divider circuit, transistors are
used in place of voltage-dividing resistors for the last few
dynodes. This method prevents the dynode-to-dynode
voltage from being affected by the photomultiplier tube signal
current, allowing good linearity to be obtained up to 60 to
70% of the voltage divider circuit current. This circuit also
features short settling time compared to when only a
Cockcroft-Walton circuit is used.
Ripple noise
Signal-to-noise characteristics
When observing the output waveform of a photomultiplier
tube, fluctuations (AC components) can be seen in the signal
components. This is so-called "shot noise" resulting from
fluctuations in the photoemission and electron multiplication
processes.
Since the effects of DC dark current can be largely
eliminated, shot noise is the dominant factor in determining
the signal-to-noise ratio (S/N ratio) in low-light-level
measurement.
To minimize the shot noise and obtain a better S/N ratio, note
the following points.
1. Use a photomultiplier tube that has as high a quantum
efficiency as possible on the wavelength range to be
measured.
2. Design the optical system for better light collection
efficiency so that the incident light is guided to the
photomultiplier tube with minimum loss.
3. Narrow the measuring system bandwidth as much as
possible, as long as no problem occurs in the measurment.
Power Supply Circuit Characteristics
Power supply circuit
There are mainly two types of power supply circuits used in
Hamamatsu PMT modules. One type is the Cockcroft-Walton
circuit. The other is an active type divider circuit combined
with the Cockcroft-Walton circuit.
Switching noise may get into the output signal of PMT
modules by induction since high-voltage power supplies in
PMT modules use a switching power supply. This induced
noise is called "ripple noise". Although Hamamatsu PMT
modules are designed to minimize this ripple noise, taking
the following measures will reduce it even further.
1) Place a low-pass filter after the signal output from the
PMT module.
2) Increase the control voltage to raise the photomultiplier
tube gain and lower the amplifier gain.
At Hamamatsu Photonics, ripple noise is measured with a
signal load resistance 1 MΩ and a load capacitance of 22 pF.
Settling time
When the control voltage for a PMT module is changed, the
high voltage applied to the photomultiplier tube also changes,
but has a slight delay due to the timing of the control voltage
input. The settling time is the time required to reach the
specified level of high voltage after changing the control
voltage. At Hamamatsu Photonics, this settling time is
measured when changing the control voltage from +1.0 V to
+0.5 V.
Voltage output type PMT modules
Using as a charge amplifier
Voltage output type PMT modules incorporate an operational
amplifier that converts a current output from the
photomultiplier tube into a voltage output. The operational
amplifier has feedback resistance and capacitance, and also
serves as a simple charge amplifier allowing pulse
measurements such as in scintillation counting applications.

Technical Guide
Technical Guide
Photosensor Module with Gate Function
Photon Counting Head
Gate operation
Principle of photon counting
When the primary excitation light from a strong light sources
enters a photomultiplier tube, the signal processing system
may saturate, causing adverse effects on the measurement.
A mechanical shutter could be used to shut off such primary
light. However, mechanical shutters are limited in terms of
high-speed operation and service life. In contrast, gate
operation is effective in serving as an electronic shutter to
gate off excessive light, by changing the dynode voltage in
the photomultiplier tube. The electronic shutter operates at
high speeds with a high extinction ratio. There are two
methods of gate operation. In one method the photomultiplier
tube is normally off and turns on when a gate signal is input.
In the other method, the photomultiplier tube is normally on
and turns off when a gate signal is input.
When light intensity becomes extremely low, light can be
counted as individual photons. Photomultiplier tubes are ideal
for photon counting because they exhibit excellent time
resolution, high gain and yet low noise. In low-light-level
measurement, photon counting has advantages over the
analog detection method. For example, noise pulses can be
easily separated, and high stability and a high S/N ratio
obtained.
Gate noise
High-speed gate pulses must be input to perform high-speed
gate operation. When a gate pulse is input to a
photomultiplier tube, induced noise is generated and appears
in the anode signal due to interelectrode capacitance. This is
called gate noise. Reducing the gate pulse voltage or noise
canceling techniques are effective to some extent in
decreasing this gate noise, but cannot completely eliminate
it. So it is necessary to increase the photomultiplier tube gain
or use the photomultiplier tube with high gain.
Switching ratio
This is the ratio of the photomultiplier tube outputs when the
gate is tuned on and off at a constant light level incident on
the photocathode. For example, while normally off operation,
if the gate-off output is 1 nA and the gate-on output is 10 µA,
the switching ratio is 1 nA to 10 µA or expressed as 1 : 104.
Quantum efficiency
The most important characteristic in photon counting is the
photocathode quantum efficiency. The probability of
photoelectron emission when a single photon strikes the
photocathode is called the photocathode quantum efficiency.
Since the number of photoelectrons emitted per photon is one
or zero, the quantum efficiency is defined as the ratio of the
number of photoelectrons emitted from the photocathode to
the number of photons incident on the photocathode over a
unit of time. There are various types of photocathodes. It is
essential to choose the photocathode that provides the
highest quantum efficiency at the wavelength to be measured.
Detection efficiency
Detection efficiency is the ratio of the number of counted
pulses (photomultiplier tube output pulses) to the number of
incident photons. The "count sensitivity" listed in this catalog is
related to this detection efficiency.
Correction of count loss
Theoretically, the maximum count rate is a reciprocal of pulsepair resolution (ability to discriminate between successive
pulses). However, since chemiluminescence and
bioluminescence occur randomly, the detected signal pulses
may overlap each other, causing a counting loss or error.
Considering the probability of pulse overlap, the maximum
effective count rate would be 1/10 th of the theoretical rate.
This count loss of overlapped pulses can be corrected by the
following equation.
N=

N : True count rate

Precautions
Safety precautions
WARNING
Subject to local technical requirements and regulations, availability of products included in this promotional material may
vary. Please consult with our sales office.
Some products listed in this catalog generate a high voltage internally. Be sure to observe the following safety
measures and take sufficient precautions to prevent possible electrical shocks.
HIGH
VOLTAGE
●Always turn off the power before moving, installing and inspecting the products or connecting/disconnecting
the cables and connectors.
●Do not modify any part of the product and do not open the housing case. Malfunctions or electrical shocks
might result and the products might overheat, smoke or catch fire.
Handling precautions
Take the following precautions when handling PMT modules.
●Do not expose the photocathode of PMT modules to excessive light such as sunlight. If exposed, noise will increase
and photocathode sensitivity will deteriorate.
●Do not touch the light input window with bare hands. Dirt and grime on the window causes loss of optical
transmittance. If the window becomes soiled with dirt or grime, wipe it clean using alcohol.
●Helium will penetrate through silica (quartz) glass windows and increase noise. Avoid using or storing those PMT
modules in an atmosphere where helium is present.
●Carefully check that the power supply output voltage and polarity are correct.
●Do not apply strong vibrations or impacts to PMT modules.
●Do not apply a strong tightening force to localized sections.
●Do not let moisture or dust penetrate inside.
●Consult with us if you must take special countermeasures against tough conditions such as high temperatures, high
humidity or strong magnetic fields.
●When designing equipment using or incorporating products listed in this catalog, install safety interlocks (breakers,
etc.) to prevent accidents from electrical shocks or excessive light input, etc.
