Photosensor Modules H10425 Series The H10425 series is a photosensor module containing a 25-mm (1") diame- ter head-on photomultiplier tube and a high-voltage power supply. It has a photosensitive area as large as 22 mm in diameter and also features a fast time response. Two products, one with a bialkali photocathode and one with a multialkali photocathode, are provided. *1: At +15 V input voltage, +1.0 V control voltage, and output current equal to dark current. *2: DAC (I2C interface) can be installed in the module. Please specify when ordering. *3: Measured at the peak sensitivity wavelength *4: Control voltage = +1.0 V *5: After 30 minutes storage in darkness *6: Cable RG-174/U, Cable length 450 mm, load resistance = 1 MΩ, load capacitance = 22 pF *7: 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. *8: No condensation Parameter Input Voltage Max.

- Electrically insulate the reference voltage output.
- Adjust the control voltage to adjust the sensitivity.
