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.
