Head-on PMT

Photon Counting Head H7360 Series

The H7360 series is a wide sensitive area photon counting head device con­taining a 25-mm (1") head-on photomultiplier tube, high-voltage power supply
circuit and photon counting circuit. Since those circuits are designed for wide
band, the H7360 series can operate at a high count rate. The high voltage
supply for photomultiplier tube and the discriminator level are preset to opti­mum values so that photon counting can be performed just by connecting a
+5 V supply and a pulse counter.
The H7360-01 is of low noise, the H7360-02 has enhanced detection efficiency
in the visible range, and the H7360-03 covers sensitivity from the visible to
near infrared.
A mount flange (E6264) is provided as an option for easy installation to
measurement equipment.
