MP 900
Ultra High Sensitivity Gateable Photon Counting Module
EVERYTHING
IN A
Description
The Photon Counting Head MP 900 series is designed for applications in all fields of single photon
detection, e.g. chemoluminescence, bioluminescence, in-vitro assay, environmental measurements
or pure research. It is an easy to use module, containing the Channel Photomultiplier, a high voltage
power supply, a discrimination amplifier and a pulse shaper for fast output pulses. An installed active
quenching systems avoids over-illumination to the detector. It is also possible to apply an external gate
function for time correlated photon counting. Strong variations in light levels are possible due to the high
dynamic range of the installed CPM. The exceptional low noise and high sensitivity facilitates detection
of extremely low light levels.
Features
• Very low noise, typical 10 cps,
• High dynamic range up to 6 orders of magnitude
• High reliability
• No cooling requirement
• Very high stability in noise level, no sudden "bursts"
• High stability over time
• Rugged and compact design
• Gateable CPM input for time resolved measurements
• Active quenching circuit for high light protection
• Extremely fast high light recovery times
• 5 volts supply voltage

CAUTION: High Voltage Warning
This product operates at high voltage. Extreme care must be taken to ensure operator safety and to avoid damage to other instruments. Avoid direct contact with the entrance
window of the built in CPM when high voltage is applied. Avoid placing conductive material close to the cathode.
