ID230 Infrared Single-Photon Detector

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.


Key Features

• 900-1700 nm 

• Adjustable quantum efficiency up to 25% 150 ps timing resolution 

• Adjustable deadtime from 2 μs to 100 μs 

• Adjustable temperature from -50°C to -90°C 

• Singlemode or multimode fibre optical input

• Best-in-class dark count rate : < 50 Hz at 10% quantum efficiency 

                                                   < 200 Hz at 20% quantum efficiency
