Description
The Channel Photomultiplier
module MH 900 series is designed
for an easy to use application for
both photoncounting and dc
operating modes. It contains an
adjustable high voltage supply and a
Channel Photomultiplier of the
C900 series.
The module also offers the
possibility to apply an external gate
function for time correlated photon
counting or active quenching
control (only bialkali types). 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 weak light levels.
Features
· High dynamic range
· No cooling required
· Very high stability in noise level
· Adjustable gain
· High stability over time
· Gateable CPM input for time
resolved measurements
· Extremely fast high-light recovery times
· Rugged and compact design
· 5 volts operating voltage
· Monitor voltage output

· 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
