Photon counting head

H10682-110W

The H10682-110W is a photon counting head device consisting of a metal package photomultiplier tube, along with a high-speed photon counting circuit and a high-voltage power supply circuit. The high voltage supply for photomultiplier tube and the discrimination level are preset to optimum values, allowing photon counting measurement by just connecting a +5 V supply. This is integrated with a newly designed condenser lens offering high light-collecting efficiency while using a thin profile.
