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.
