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. 60 product variations specifications head-on pmt photon counting head h7360 series (at +25 c) parameter input voltage max. input voltage max. input current effective area peak sensitivity wavelength count sensitivity count linearity * 1 dark count * 2 pulse-pair resolution output pulse width output pulse height * 3 recommended load resistance signal output logic operating ambient temperature * 4 storage temperature * 4 weight +4.75 to +5.25 +6 140 22 420 2.3 10 5 4.1 10 5 3.4 10 5 5.7 10 4 6.0 10 6 60 300 18 9 3 50 positive logic +5 to +40 -20 to +50 140 25 420 2.1 10 5 2.5 10 5 2.0 10 5 1.3 10 5 7.8 10 4 5000 15000 h7360-02 h7360-03 h7360-01 375 1.4 10 5 2.7 10 5 1.7 10 5 4.6 10 4 15 80 unit v v ma mm nm s -1 ?w -1 s -1 s -1 ns ns v ? c c g *1: random pulse, at 10 % count loss *2: after 30 minutes storage in darkness *3: with input voltage +5 v, load resistance 50 ? *4: no condensation 300 nm 400 nm 500 nm 600 nm 700 nm ty p. max. ty p. ty p. main body mount flange type no. h7360-01 h7360-02 h7360-03 300 nm to 650 nm 300 nm to 850 nm low noise high detection efficiency for visible to near ir range spectral response features this product can't be used at vacuum environment or reduced pressure environment.
