Compact Head-on PMT Photosensor Modules H7827 Series The H7827 series photosensor modules incorporate a 19-mm (3/4") diameter head-on photomultiplier tube, a high-voltage power supply circuit and a low noise amplifier. Two types of amplifiers are available with a current-to-voltage conversion factor of 1 V/µA or 0.1 V/µA and a frequency bandwidth of DC to 20 kHz or DC to 200 kHz. Compared to other PMT modules, the H7827 series has higher resistance to vibration and shock, making them suitable for portable or mobile measurement equipment.
