Compact Side-on PMT
Photosensor Modules H7711/H7712/H8568/H8569 Series
The H7711/H7712/H8568/H8569 series photosensor modules incorporate a
13-mm (1/2") diameter side-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 coefficient of 1 V/µA or 0.1 V/µA and a
frequency bandwidth of 20 kHz or 200 kHz. Because of different characteristics of the power supply circuit, the H7711/H7712 series features low power
consumption, while the H8568/H8569 series offers fast settling time. Five
types of photomultiplier tubes are provided as standard lineups to meet various needs for spectral response range.
