Photosensor module

H11900-20

null

The H11900 and H11901 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 H11900 series are lead pin output type, while the H11901 are flexible cable output type.

+5V input type H10720/H10721 series are available.
