ROF Si photondetector avalanche photodiodes free running single photon detector

Short Description:

This product is a visible light band single photon detector（Photodetector）. The core device uses SiAPD, integrates optical, structural, electrical and software technologies, and has the characteristics of high detection efficiency, strong maintenance and strong environmental adaptability. It is widely used in the fields of single photon Lidar, fluorescence detection, single photon imaging and quantum key distribution. This product uses Si avalanche photodiodes operating in Geiger mode for single photon detection in visible wavelengths. Among them, the typical detection efficiency of 850nm single photon is >50%, dark count
<150cps, after pulse ≤5.5%, time jitter < 500ps. In addition, for specific application scenarios, support for the refrigeration target temperature, dead time and other parameters of the user configuration function to strengthen the detection efficiency, saturation count rate and other specific indicators.
