Photon counting head
The H10682 series 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.
The H10682 series has also over light detection function to output a signal at the state that an output count falls by excessive incident light. By this signal, measurement data can be judged that it is normal or not.
