Optical Photon Detection System with Superconducting Detectors for Precise Measurements

The system of registration of optical photons on the basis of a closed-cycle refrigerator (hereinafter, registration system) is a complete device based on the action of optical radiation (visible and infrared part of the spectrum). The registration system may contain up to 16 registration channels, each of which is designed for single-photon detection of optical radiation quanta.
