  • Avalanche Detector for Highest Sensitivity
  • Extremely Short Rise Times
  • Easy-to-use Package


Originally developed for the detection of the beat note signal between cw or pulsed lasers, the APD310 is ideally suited for applications requiring highest sensitivity for low level input signals. The APD avalanche photodiode series can provide an extremely sensitive alternative to traditional PIN photodiodes. It is also fast enough for the characterization of, for example, pulsed solid-state lasers on the nanosecond time scale. It maintains high gain stability over the 10 °C to 40 °C temperature range by utilizing a temperature compensation circuit, which adjusts the ~150 V DC bias to ensure operation near the breakdown voltage.
