For applications that require greater sensitivity than can be attained with traditional PIN photodiodes, the APD Series Avalanche Photodiodes can provide an extremely sensitive alternative. The APDs are sensitive enough and fast enough for the characterization of pulsed lasers on the nanosecond scale.

The APD210 silicon APD provides exceptional performance for low light level applications in the 400 to 1000nm range, while the APD310 covers the InGaAs range of 850-1650nm. The APD maintains high gain stability over the 0° to 40°C temperature range by utilizing a temperature compensation circuit which adjusts the -150 VDC bias to ensure operation near the breakdown voltage. A 40dB gain amplifier is integrated into the package and is AC coupled to the output BNC. The output is matched to a 50Q impedance. The detector has an electronic bandpass of 1MHz to 1GHz and offers a user accessible potentiometer providing a continuous gain adjustment.

The APD Series has SM05 threads for easy integration into Thorlabs entire family of lens tubes and cage assemblies. The bottom of the detector has a metric

mounting. The compact packaging allows the APD to be directly substituted
