Side-on PMT
Photosensor Modules H8249 Series
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 coefficient 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.
