Hamamatsu Photonics K.K. is a Japanese manufacturer of optical sensors, electric light sources, and other optical devices and their applied instruments for scientific, technical and medical use.
Image intensifiers
Hamamatsu mostly manufactures intensifier tubes for scientific purposes, but also image intensifiers for use in night vision devices. Gen2+ and Gen3[1]. Hamamatsu currently develops two image intensifiers with power supplies included, the V6833P and the V7090P with a -G option for the 6833 for Autogating.[2]
