APD Avalanche Photodetector module
Product introduction
HC-APRM series APD avalanche photodetection module adopts imported APD avalanche photodiodes with high gain, fast response and low dark current. It integrates low-noise broadband transimpedance amplifier, boost and temperature compensation circuits, and has the characteristics of high gain and high sensitivity. The power supply of the module is positive 12 V, and the input optical interface can be optical fiber interface or space incidence. The optical fiber interface is a universal interface for single-mode and multimode optical fibers; multiple photosensitive surfaces can be selected during space incidence, and the external thread adapter for external optical antenna is provided as standard; the electric signal is output from the SMA port, which is very suitable for the detection of weak light signals and the measurement of short pulse signals, and is mainly used in the fields of optical detection, space laser communication, laser radar, distributed optical fiber sensing system, etc.
