Photomultiplier tube module


The H7826 series photomultiplier tube 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.
