Photosensor module



The H10723 series is a photosensor module containing a metal package PMT, a low-power consumption high-voltage power supply circuit, and a low-noise amplifier. The amplifier converts the PMT current output to a voltage output so that signal can be easily processed. Also, the amplifier is connected close to the PMT anode output pin to make the signal less affected by external noise. The H10723 series covers a frequency bandwidth from DC to 200 kHz, which is wider than that for the H10722 series.

+15V input type H11903 series are available.
