Metal Package PMT with Gate Function
Photosensor Modules H12056 Series
The H12056 series is a photosensor module containing a metal package
PMT, shutter circuit and a high-voltage power supply circuit. This module has
shutter function to avert the PMT from excessive light without switching OFF
the PMT voltage completely like the case of opening / closing machine to
change the measurement samples. Three types of photocathodes are avail-
able, including a super bialkali photocathode that has higher sensitivity than
conventional bialkali photocathodes, a multialkali photocathode with sensitivi-
ty extending to the near infrared region, and a red sensitivity enhanced multi-
alkali photocathode. Hamamatsu also provides "P" type with gain and low
dark count selected for photon counting measurement.
