H12386 Series Photonic Counting Head PMT Module

The H12386 series is a photon counting head device consisting of a metal-encapsulated photomultiplier with a high-speed photon counting circuit and a high-voltage power supply circuit. The photomultiplier's high-voltage power supply and discrimination level are optimally preset, allowing photon counting measurements to be performed by simply connecting to a +5 V power supply.
The H12386 series also has an incident light excess detection function that outputs a signal when the output count drops due to excessive incident light. This signal can be used to determine whether the measurement data is normal or not.
