Channel Photomultipliers and Modules
MP Series Photon Counting Modules
Ultra High Sensitivity Gateable
Photon Counting Module
T E E H S A T A D
Description
The Photon Counting Head MP 900 series is designed for applications in all fields of single photon detection, e.g. chemoluminescence, bioluminescence, flourescence, in-vitro ssay,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 system avoids overillumination 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
·High dynamic range
·No cooling required
·Very high stability in noise level
·Active quenching circuit for high light protection
·Gateable CPM input
·Optical fiber read-out possible
·5 volts operating voltage
·Monitor voltage output
