Customized Photomultiplier Module Head HM (Anode signal out)

The Customized Photomultiplier module HM – series (Anode signal out) is designed for an easy to use application for both photoncounting and analogue dc operating modes. It contains an adjustable high voltage supply and a Customized Photomultiplier of the C – series. The module offers also the possibility to apply an external gate function for time correlated photon counting or active quenching control. 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.
