Si Avalanche Photodiode (APD) Series 400-1100nm

The Si avalanche photodetector module integrates a low-noise APD detector, a low-noise broadband transimpedance amplifier, ultra-low-noise isolated power supply, high-voltage power supply, and APD temperature compensation. The isolated power supply ensures that the output signal is not affected by external power sources. APD temperature compensation improves the stability of the detection module. The avalanche photodetector features high gain, high sensitivity, high bandwidth, and low noise characteristics.

Product features：Low noise, high gain、 Built-in high-voltage power supply、 APD temperature compensation、 Compact structure、 Built-in low-noise isolated power supply

Application area：Fiber optic sensing、 Fiber optic communication、 Laser ranging、 Spectral measurement、 ns-level optical pulse detection
