photosensor modules h7732 series product variations specifications the h7732 series photosensor modules consist of a 28-mm (1-1/8") diameter side-on photomultiplier tube and a high-voltage power supply. these side-on photomultiplier tubes have long been used for spectroscopic applications and provide high gain and high sensitivity. five types of photomultiplier tubes are provided as standard lineups to meet various needs for spectral response range. connectors are used for power input and signal output. by selecting cables in convenient length, the h7732 can be easily installed inside equipment or re- moved from equipment. the h7732 is a general-purpose type and the h7732-01 is a low-noise type. the h7732-10 is sensitive over a wide range from uv to near infrared and has particularly high sensitivity in wavelengths above 600 nm. the h7732p- 01 and h7732p-11 are selected as low dark count types ideal for photon counting and low-light-level measurement. *1: measured at the peak sensitivity wavelength *2: control voltage = +1.0 v *3: after 30 minutes storage in darkne ss *4: control voltage: plateau voltage *5: cable rg-174/u, cable length 450 mm, load resistance = 1 m ?, load capacitance = 22 pf *6: the time required for the output to reach a stable level following a change in the control voltage from +1.0 v to +0.5 v. *7: no condensation type no. h7732 h7732-01 h7732-10 H7732P-01 h7732p-11 300 nm to 650 nm 185 nm to 680 nm 185 nm to 900 nm 185 nm to 680 nm 185 nm to 850 nm for general applications in visible range low noise in uv to visible range high sensitivity in uv to near ir range. uses photomultiplier tube with meshless grid for excellent uniformity. for photon counting spectral response features parameter h7732-10 input voltage max. input voltage max. input current max. output signal current max. control voltage recommended control voltage adjustment range effective area sensitivity adjustment range peak sensitivity wavelength rise time * 2 ripple noise * 2 * 5 (peak to peak) settling time * 6 operating ambient temperature * 7 storage temperature * 7 weight +11.5 to +15.5 +18 40 100 +1.2 (input impedance 100 k ? ) +0.3 to +1.1 4 20 1: 10 4 140 250 0.3 74 400 2500 7.4 10 5 3 50 2.2 0.5 0.2 +5 to +45 -20 to +50 220 400 h7732-01 40 60 6.4 60 200 400 4.0 10 5 0.1 2 h7732 30 60 7.1 60 50 600 6.0 10 5 5 50 H7732P-01 40 60 6.4 60 200 400 4 10 5 0.1 0.5 30 80 h7732p-11 430 140 200 0.15 80 300 700 2.8 10 5 0.2 1 80 200 unit v v ma a v v mm nm a/lm ma/w a/lm a/w na s -1 ns mv s c c g min. ty p. ty p. ty p. ty p. min. ty p. ty p. ty p. max. ty p. max. ty p. max. max. luminous sensitivity blue sensitivity index (cs 5-58) red/white ratio radiant sensitivity * 1 luminous sensitivity * 2 radiant sensitivity * 1 * 2 dark current * 2 * 3 dark count * 3 * 4 cathode anode
