Metal package PMT
Photosensor Modules H10722 Series
The H10722 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
the signal can be easily processed. Also, the amplifier is connected close to the
PMT anode output pin in order to make the signal less affected by external noise.
Four types of photocathodes are available, including a super bialkali
photocathode that has higher sensitivity than conventional bialkali photocathodes,
an ultra bialkali photocathode that offers even higher sensitivity, a multialkali
photocathode with sensitivity extending to the near infrared region, and a red
sensitivity enhanced multialkali photocathode.
