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.
