Metal package PMT Photon Counting Head H10682 Series 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 H10682-110 has the super bialkali (SBA) photocathode and the H10682-210 has the ultra bialkali (UBA) photocathode, so they have higher sensitivity than conventional photon counting heads. 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.
