| 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.
