This product is a visible light band single photon detector. The core device adopts SI APD, which integrates optics, structure, electricity and software technology, and has the characteristics of high detection efficiency, strong maintainability and strong environmental adaptability.
Single-photon detection in visible light band is performed by using SI avalanche photodiode working in Geiger mode. Among them, the typical detection efficiency of 850nm single photon is > 50%, dark count < 150 cps, afterpulse ≤5.5%, and time jitter < 500 ps. In addition, according to specific application scenarios, it supports user configuration functions of cooling target temperature, dead time and other parameters to strengthen specific indicators such as detection efficiency and saturation count rate.
