APD Detectors

An APD detector, or avalanche photodiode detector, is a type of photodetector used to detect light or optical signals by converting incoming photons into electrical current. It operates based on the principle of avalanche multiplication, which allows it to achieve higher sensitivity compared to conventional photodiodes. Learn more about APD detectors →
