Head-on PMT

Photon Counting Head H11870 Series

The H11870 series is a wide sensitive area photon counting head device

containing a 25 mm (1") diameter head-on photomultiplier tube, a high-vol-

tage power supply circuit and a photon counting circuit. The high voltage sup-

ply for photomultiplier tube and the discrimination level are preset to optimum

values, allowing photon counting measurement by just connecting a +5 V

supply. The H11870 series has a function of over light detection output for in-

dicating the excessive light operating condition.

A mount flange (E6264) is provided as an option for easy installation to

measurement equipment.
