Photomultiplier tube module


The H9305 series photomultiplier tube modules contain a high-voltage power supply circuit and a 13-mm (1/2") diameter side-on photomultiplier tube in a compact aluminum housing. The 13-mm (1/2") side-on photomultiplier tube has a reflection mode photocathode, an adequate gain of more than 10e(6) and fast time response. High S/N ratio can be obtained even when measuring extremely low level light at high speeds.The H9305 series uses a Cockcroft-Walton circuit with low power consumption. Flexible cables are used for easy installation in equipment.
