H10720-01Photosensor module

The H10720 and H10721 series are photosensor modules containing a metal package PMT and a high-voltage power supply circuit. The built-in PMT uses a metallic package with the same diameter as a TO-8 metal package used for semiconductor photodetectors. Despite the small size nearly equal to photodiodes, this PMT delivers high gain, wide dynamic range, and high-speed response. Hamamatsu also provides "P" type with low dark count selected for photon counting measurement. The H10720 series are lead pin output type, while the H10721 are flexible cable output type.

+15V input type H11900 / H11901 series are available.
