The H10723 series are photosensor modules 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 effected by external noise. The H10723 series cover a frequency bandwidth from DC to 200 MHz, which is wider than that for the H10722 series.

Four types of photocathodes are available including a super bialkali photocathode that has higher sensitivity than conventional bialkalki photocathodes (H10723-110), an ultra bialkali photocathode that offers even higher sensitivity (H10723-210), a multialkali photocathode with sensitivity extending to the near infrared region (H10723-01) and a red sensitivity enhanced multialkali photocathode (H10723-20).
