Head-on PMT
Photosensor Modules H10425 Series
The H10425 series is a photosensor module containing a 25-mm (1") diameter head-on photomultiplier tube and a high-voltage power supply. It has a
photosensitive area as large as 22 mm in diameter and also features a fast
time response.
Two products, one with a bialkali photocathode and one with a multialkali
photocathode, are provided.
