The ID230 is a major breakthrough for singlephoton detection in free-running mode at telecom wavelengths. Based on the existing ID220, this new series offers a significantly decreased dark count rate thanks to an improved cooling system and adapted electronics. The avalanche photodiode working in Geiger mode is cooled down to -90°C. This series has been especially designed for applications in which asynchronous photon detection is essential.

The module can operate at detection probability levels of up to 25%, with a deadtime that can be set between 2 μs and 100 μs. The photon arrival time is reflected by a 100 ns LVTTL pulse, with a timing resolution of below 150 ps at 25% efficiency. A simple USB interface allows the user to set all parameters.
