PMT-175 has SbKCs photocathode and linear 14-dynode multiplication system. The device is intended for multispectral research, and can be used for special purpose equipment and gas sensors.
Constructive design:
PMT-175 is produced in a glass balloon with head-on optical input. The input window is made of boron-silicate UV glass. Available complete set: socket and voltage divider.
