Compact Head-on PMT
Photosensor Modules H7826 Series
The H7826 series photosensor modules consist of a 19-mm (3/4") diameter
head-on photomultiplier tube and a high-voltage power supply circuit. The
length of the photomultiplier tube used here is short compared to other photomultiplier tubes of the same diameter, making it compact even though it has a
large light input diameter of 15 mm. The H7826 series also has excellent resistance to vibration and shock compared to other photomultiplier tubes,
making it ideal for use in portable equipment.
