Ultra High Sensitivity Gateable Photon Counting Module
Description
NEW
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.

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.
