Photomultiplier (CPM) Modules
(CPM TE Cooled Counting Module)

Photon Counting TE cooled Module CMC (TTL-out)

The Photon Counting Head CM(C) series is designed for applications in all fields of single photon detection, e.g. chemo luminescence, bioluminescence, in-vitro assay, environmental measurements or pure research. It is an easy to use module, containing the Customized Photomultiplier (CPM), a high voltage power supply, a discrimination amplifier and a pulse shaper for fast output pulses. In addition, the CMC version is equipped with a TE cooling system consisting of Peltier device, temperature control and cooling fan. Thus, the overall characteristics can even be improved. The CPM dark noise can be further lowered and temperature of the CPM can be highly stabilized. The latter improves the stability of the system under changing environmental conditions. An installed active quenching system 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 weak light levels.
