MP 96X-2/ MP 97X-2 CPM Module
Single Photon Counting Module
for Particle Measurement
Description
The Photon Counting module series
MP96X-2 / MP97X-2 is specially
designed for particle measurement with
530 nm and 632 nm lasers. Based on the
standard multialkali photocathode, the
sensitive diameter is reduced to 2mm in
order to achieve an excellent low dark
count performance. With an optional
SMA adapter, also a fiber read out is
possible.
The MP96X-2/MP97X-2 series satisfies
by exceptional low after pulses. 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 over- illumination to the detector.
Features

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.
Ensure that no light levels are applied, generating higher anode currents than specified.
All given values are nominal/typical @ 20 °C ambient temperature; specification subject to change without notice
