H7680

Gated PMT Modules H7680/-01 The H7680/-01 PMT modules are capable of high-speed, high-repetition gated operation. An optimum design in the combination of circuit and photomultiplier tube delivers excellent gating characteristics including a minimum gate width of 30 ns (H7680-01), 100 kHz repetition rate, and a gate extinction ratio of 107. The H7680/-01 can operate on a low +15 V supply because of incorporating high-voltage power suppy circuit. And, the incorporated PMT gain can be controled by adjusting the control voltage between +2 V to +5 V.
