Mini-spectrometers
Mini-spectrometers are compact spectrometers (polychromators) whose optical system, image
sensor, and circuit are condensed into a small case.
Previous spectroscopic instruments used in the chemical analysis field and the like have been
typically large and expensive. In contrast, mini-spectrometers are compact and portable, making it
possible to take real-time measurements on-site, rather than having to bring in measurement
samples into a room in which a spectroscopic instrument is installed.
This miniaturization also made it possible to incorporate them into various types of equipment. They
are used in environmental measurement instruments, color measurement instruments, production
lines, information devices and so on.
Hamamatsu provides more than 20 types of mini-spectrometers that cover the spectral range
from UV to near infrared. Further, Hamamatsu offers ultra-compact types that allow them to be
installed in mobile devices and collaborate with portable devices.

MOEMS technology that underlies mini-spectrometers
The mini-spectrometer is a product that integrates Hamamatsu’s MOEMS (micro-opto-electro-mechanical-systems) technology,
which combines optical technology including opto-semiconductor devices and optical systems and MEMS technology, with circuit
and software.
The detector serving as the core of the mini-spectrometer is a proven Hamamatsu image sensor in analysis and measurement
fields. Since Hamamatsu develops its own grating, which performs spectroscopy, grating with various specifications (high resolution, wide spectral range, high diffraction in the ultraviolet region, etc.) can be mounted on its mini-spectrometers.

Technical information
the more the spectral resolution is improved, but the throughput
becomes lower. An optical fiber is connected to the minispectrometer input slit.
Structure
1
Wavelength dispersive spectrometers are broadly grouped into
monochromator and polychromator types. Monochromators use
a grating as the wavelength dispersing element for separating the
incident light into a monochromatic spectrum. Polychromators
utilize the principle of monochromators and are designed to allow
simultaneous detection of multiple spectra. Mini-spectrometers
fall under the polychromator type. In monochromators, an exit
slit is usually formed on the focal plane of a focus lens, while in
polychromators an array type detector (image sensor) is placed
along the focal plane of the focus mirror/lens. To make minispectrometers compact, the polychromators use a collimating lens
and focus mirror/lens with a shorter focal distance compared to
monochromators.
Collimating mirror/lens
The light passing through the input slit spreads at a certain angle.
The collimating mirror/lens collimate this slit transmitted light
and guide it onto the grating. At this point, an aperture (aperture
mask) is used along with the collimating mirror/lens to limit
the NA (numerical aperture) of the light flux entering the minispectrometer.
Grating
The grating separates the incident light guided through the
collimating mirror/lens into each wavelength and lets the light
at each wavelength pass through or be reflected at a different
diffraction angle. There are two types of gratings for minispectrometers: transmission type and reflection type.

KACCC0256EA
The function of each component is explained below.
Image sensor
Input slit
The image sensor converts the spectrum of light focused according
to each wavelength by the focus mirror/lens into electrical signals,
and then outputs them. Cooled mini-spectrometers incorporate a
thermoelectrically cooled image sensor to reduce image sensor
noise.
The input slit is the opening for receiving the light to be measured.
The input slit restricts the spatial spread of the measurement light
that enters the mini-spectrometer, and the slit image of the incident
light is focused on the image sensor. The narrower the input slit,
Micro-spectrometer configuration
Besides a CMOS image sensor chip integrated with an optical slit by etching technology, the micro-spectrometer employs a reflective concave brazed
grating formed by nanoimprint. The glass used in the light path of the previous products is not used, making it extremely compact.

Mini-spectrometers
However, narrowing the slit width and reducing the NA will
limit the light incident on the mini-spectrometer. The light level
reaching the image sensor will therefore decrease.
For example, when comparing the C10082CA with the
C10082CAH, the slit width of the C10082CA is 70 μm while that
of the C10082CAH is 10 μm, which is 1/7 of the C10082CA.
This means that the light level passing through the slit of the
C10082CAH is 1/7 of the C10082CA.

Spectral resolution
(1) Definition of spectral resolution
The spectral resolution of mini-spectrometers is defined based on
the full width at half maximum (FWHM). FWHM is the spectral
width at 50% of the peak power value as shown in Figure 2. Figure
3 shows examples of spectral resolution measured with different
types of mini-spectrometers.

(2) Changing the spectral resolution
The spectral resolution of mini-spectrometers varies depending
on the slit width and NA. In the C10082CA, for example, the slit
width is 70 μm and the NA is 0.22. Figure 4 shows typical examples
of spectral resolution when the NA is changed to 0.11 and the slit
width is narrowed. This proves that the spectral resolution can be
improved down to about 1 nm by changing conditions.

(3) Spectral detection width assigned per pixel of image sensor
This section describes the spectral detection width that is assigned
per pixel of the image sensor mounted in a mini-spectrometer. The
spectral detection width is different from spectral resolution. The
approximate spectral detection width assigned per pixel is obtained
by dividing the spectral response range by the number of pixels of
the image sensor.
• Example: C10082CA
(spectral response range: 200 to 800 nm, 2048 pixels)
Spectral detection width assigned per pixel = (800 - 200)/2048 ≈ 0.3 nm··· (1)
The detection wavelength of any given pixel is calculated from
equation (2) using the wavelength conversion factor that is written
in the EEPROM in the mini-spectrometer. This allows obtaining
the wavelength assigned to any pixel.
Detection wavelength of any given pixel [nm] = a0 + a1pix + a2pix2 + a3pix3 + a4pix4 + a5pix5··· (2)
a0 to a5: wavelength conversion factor
pix: any pixel number of image sensor (1 to the last pixel)
Definition of stray light
There are two methods to define stray light: one method uses a
long-pass filter and the other method uses reference light in a
narrow spectral range (light output from a monochromator or line
spectra emitted from a spectral line lamp, etc.).
The long-pass filter method uses light obtained by making white
light pass through a long-pass filter for particular wavelengths.
In this case, the stray light is defined as the ratio of transmittance
in the “wavelength transmitting” region to transmittance in the
“wavelength blocking” region. The stray light level (SL) in this
case is defined by equation (3). (See Figure 10 for the definitions
of Tl and Th.)
SL = 10 × log(Tl/Th) ············ (3)
This definition allows measuring the effects of stray light over
a wide spectral range and so is used as an evaluation method
suitable for actual applications such as fluorescence measurement.
However, be aware that the intensity profile of white light used as
reference light will affect Tl and Th values.
[Figure 10] Definitions of Tl and Th
[Figure 9] Finding the center wavelength of line spectrum by
approximation
Th
Transmittance
Hamamatsu mini-spectrometers are designed so that the spectral
width assigned per pixel in the image sensor is small relative to the
spectral resolution. When a line spectrum is measured with a minispectrometer, the output is divided into multiple pixels as shown in
Figure 9. The center wavelength of the line spectrum can be found
by approximating this measurement result with a Gaussian curve.

In the other method using reference light in a narrow spectral
range, the stray light level is defined by equation (4).

Stray light
This definition is not affected by the reference light because the
measurement conditions are simple.
In both definition methods, the stray light conditions will differ
depending on the wavelength to be detected. The stray light should
therefore be measured at multiple wavelengths.
Stray light is generated as a result of extraneous light entering
the detector (image sensor), which should not be measured. The
following factors can generate stray light.
• Fluctuating background light
• Imperfections in the grating
• Reflection from lens, detector window, and detector photosensitive
area

[Figure 11] Examples of stray light measurement using line
spectra (C11482GA)
The output charge of an image sensor is converted into a voltage
by the charge-to-voltage converter circuit and then converted into
a digital value by the A/D converter. This is finally derived from
the mini-spectrometer as an output value. The output value of a
mini-spectrometer is expressed by equation (6).

Operation mode
Free-run operation (normal operation mode)
When light enters an image sensor, an electrical charge is
generated in each pixel of the image sensor according to the
incident light level. This charge accumulates in each pixel during
the integration time and is cleared to zero when read out. This
means that the charge must be read out before starting integration
of newly generated charges. In mini-spectrometers, this cycle of
“charge integration → charge readout (A/D conversion) → digital
data hold” repeats in a cycle. Digital data is constantly updated
with data obtained in the latest integration time. When a data
request is received from the PC, the mini-spectrometer sends the
latest data at that point to the PC. Figure 13 shows the free-run
operation.

Operation mode when trigger is input
[TM/TG series (USB 1.1 compatible)]*1
The TM/TG series mini-spectrometers (USB 1.1 compatible)
that support external trigger operation can acquire data based on
external trigger signal input.
The external trigger function works with DLL, but does not
function on the supplied evaluation software. Therefore, when
using an external trigger function, the user software must be
configured to support that function.
Use the A10670 coaxial cable for external trigger (sold separately)
to connect the mini-spectrometer to a device that outputs digital
signals at 0 V to 5 V levels.

Operation modes using external trigger input are described below.
(1) Data hold by external trigger input
This operation mode differs from free-run operation in that data
to be held is controlled by trigger input. The mini-spectrometer
internally holds digital data accumulated during the integration
time that begins just after the trigger input edge (rising or falling
edge can be specified). This data being held is then reset when it is
read out from the PC. If the next trigger is input while the data is
still being held, then that data is updated to new digital data.
For example, when a mini-spectrometer is used to detect light
emitted from a DC mode light source with a shutter installed,
then data accumulated in a predetermined integration time can be
held by supplying the mini-spectrometer with a trigger input for
shutter open operation. Measurements can be made under high
repeatability conditions by setting a shutter open period that is
sufficiently longer than the integration time.

(2) Data labeling during external trigger input
This operation mode attaches a label to digital data during the
gate period for external trigger input. A label is attached to
digital data during trigger input (high level or low level can be
specified). When the digital data is read out from the PC, the label
information can be obtained at the same time.

When acquiring data under different measurement conditions,
this mode is suitable for identifying which measurement
condition applies to the measurement data. For example, suppose
measurements are made under condition A and condition B.
Condition A uses no trigger input to make measurements, so there
is no labeling. In contrast, condition B uses a trigger input, so a
label is attached to the acquired data. Labeling the acquired data
in this way during trigger input makes it possible to distinguish
between acquired data measurement conditions.
Data integration starts when an external trigger edge (rising or
falling edge can be specified) is applied to the trigger connector,
and then the digital data is acquired.

The evaluation software has measurement modes including
Monitor, Measure, Dark, and Reference. Table 5 shows the
features of each mode. Data measured in Measure mode, Dark
mode* 4 , and Reference mode* 4 can be saved in csv format
(loadable into Microsoft® Excel®).
Table 6 shows the arithmetic functions of the evaluation software,
and Table 7 shows limitations on setting parameters during
measurement.
*3: A factor for converting the pixel numbers of the image sensor to wavelengths. However, a factor for converting the count values after A/D conversion into incident light levels is not available.
Evaluation software types
The following five types of evaluation software are available. Each
type can only be used for specific mini-spectrometers.
• For the TM/TG series (USB 1.1 interface)
• For the TM/TG/TF series (USB 2.0 interface)
*4: The C11118GA, C11697MB, C11482GA, C11351 series, and C13016 do not

Supplied CD-ROM
Mini-spectrometers come with DLLs. By using this DLL,
users can create Windows applications for controlling minispectrometers in a software development environment such as
Visual C++ and Visual Basic*4 *5. Because Windows application
software cannot directly access a USB host controller, the
necessary functions should be called from the DLL to allow
the software to access the USB host controller via the USB
driver and to control the mini-spectrometer (see Figure 25). The
DLL provides functions for opening/closing USB ports, setting
measurement conditions, getting data and module information, and
so on.

measurement utilizing white light interferometry, a rippling
interference spectrum is obtained due to reflections between the
front and back surfaces of the film. The film thickness can then be
determined by calculation from the spectral peak count, wavelength
range, refractive index of film, and the angle of incident light.
