Head-on PMT

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.

*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 M

Ω, 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
