AD200 is a compact and affordable single-photon detector module with a built-in counter. The AD200 is based on a reliable silicon avalanche photodiode sensitive in the visible spectral range. The detector of the AD200 has high efficiency values in the near visible region (around 650 nm). The AD200 features active quenching and full digital temperature control. A separate power supply is provided as standard.
