Photodetectors

Photodetectors of SSS Optical Technologies (SSSOT) are designed and built for easy operation. Exceptionally high sensitivity in combination with fast response, small size, and the lack of expensive external high voltage power supply (typical for traditional vacuum photo-multiplying tubes – PMTs) are just few of many attractive features.
