Near Infrared Single Photon Detector STRSPD-305

NIR Single Photon Detector (900-1700)-STSPD-305 workin pulse gated mode. Extremely weak light detection module, SPAD based on InGaAs/InP process, can achieve single photon level.Optical pulse detection and counting, with high detection efficiency, low dark counting rate, low post-pulse probability and othercharacteristics point. The module is small and beautiful, with a simple and easy-touse interface. It uses the USB serial port as the host computer data.

The communication interface can also be used directly to detect the output pulse signal and be connected to the system or counter for use. Supports up to 100MHz external trigger frequency.

Features
• Modular type, compact and beautiful, stable performance
• Maximum 100MHz gate repetition frequency
