PHOTON COUNTING HEADS H12386 SERIES

Product catalog summary

Overview
The H12386 series by Hamamatsu is a photon counting head device that integrates a photomultiplier tube, a high-speed photon counting circuit, and a high-voltage power supply circuit. It is designed for easy photon counting measurements with a simple +5 V supply connection. The series includes an over light detection function to ensure measurement accuracy by signaling when output counts are affected by excessive incident light.

Product Variations
The series includes three models: H12386-110, H12386-210, and H12386-01. Each model varies in spectral response and photocathode type:

H12386-110: Spectral response from 230 nm to 700 nm, super bialkali photocathode.
H12386-210: Spectral response from 230 nm to 700 nm, ultra bialkali photocathode, offering higher sensitivity.
H12386-01: Spectral response from 230 nm to 870 nm, multialkali photocathode, suitable for visible to near IR range.

Specifications
Key specifications for the H12386-210 model include:

Input voltage: +4.75 to +5.25 V
Max input voltage: +6 V
Max input current: 40 mA

PHOTON COUNTING HEADS H12386 SERIES OVERVIEW The H12386 series is a photon counting head device consisting of a metal package photomultiplier tube, along with a high-speed photon counting circuit and a high-voltage power supply circuit. The high voltage supply for photomultiplier tube and the discrimination level are preset to optimum values, allowing photon counting measurement by just connecting a +5 V supply. The H12386 series has also over light detection function to output a signal at the state that an output count falls by excessive incident light. By this signal, measurement data can be judged that it is normal or not.
