Photomultiplier tube module


The H11706-40 is an optical sensor module containing a metal package photomultiplier tube, a high-voltage power supply circuit, and a gate circuit. The gate circuit electrically protects the photomultiplier tube from excessive light such as excitation light that illuminates samples. The H11706-40 has GaAsP photocathodes with high sensitivity in the visible region. The H11706-40 also includes “P type” with high gain and low dark count specifically selected for photon counting applications.
