Compact Head-on PMT
Photosensor Modules H7827 Series
The H7827 series photosensor modules incorporate a 19-mm (3/4") diameter
head-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. Two types of photomultiplier tubes with different
spectral response characteristics are provided for measurement in the visible
range or visible to near IR range.
