H7360

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.
