Head-on PMT
Photon Counting Head H7360 Series
The H7360 series is a wide sensitive area photon counting head device con-
taining a 25-mm (1") diameter head-on photomultiplier tube, a high-voltage
power supply circuit and a 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.
