Photomultiplier tube PMT-186, PMT-186-1

PMT-186 (PMT-186-1) has SbKNaCs photocathode and linear 14-dynode multiplication system. PMT-186-1 also has two pre-photocathode grids before the first dynode, it can work in a controlled mode. The device is intended for registration of pulse  signals within visible and near IR ranges for multispectral research.

Construction design
PMT-186, PMT-186-1 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.
