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 also has excellent resistance
to vibration and shock compared to other photomultiplier tubes, making it
ideal for use in portable equipment.
