Photosensor Modules

H8249 Series

Specifications

The H8249 series photosensor modules incorporate a 28-mm (1-1/8")

diameter side-on photomultiplier tube, a high-voltage power supply circuit and

a low noise amplifier. Two types of amplifiers are available with a current-to-

voltage conversion factor of 1 V/

µA or 0.1 V/µA and a frequency bandwidth of

DC to 20 kHz or DC to 200 kHz. Three types of photomultiplier tubes are

provided as standard lineups for general applications in the visible range, UV

to visible range requiring low-noise, and UV to near IR range.
