Buying Avalanche Photodiodes
Avalanche photodiodes (APDs) are highly sensitive semiconductor-based photodetectors capable of detecting weak optical signals and single photons, often in Geiger mode. They are used in applications requiring precise low-light detection, such as quantum optics, biomedical imaging, and LIDAR systems.
