id230 NIR Single Photon Counter

id230 is free running single photon detector operating in NIR 900-1700nm and has best dark cout rate.

Specially for the applications which require asynchronous photon detection, IDQ has developed and offers a new series of single photon detectors operating in free-running mode. ID230 is an infrared single-photon counter, a photon detector with the best-in-class dark count rate, free-running mode at telecom wavelengths and adjustable quantum efficiency up to 25%.

This unique for single photon detection product based on InGaAs/InP avalanche photodiode working in Geiger mode provides fast avalanche quenching. That limits afterpulsing and allows you to run operations at reasonably short deadtimes which can be set between 1us and 100us. In addition, a new cooling system enabling to go down up to – 100 °C gives the infrared single photon detector ID230 the lowest dark count rate available at the market.

Low afterpulsing and dark count rate are combined with the best timing jitter and the highest quantum efficiency. The photon counting module can operate at detection probability levels of up to 25%. The photon arrival time is reflected by a 100ns LVTTL pulse what makes ease of combination of a photon detector with other electronic devices within your research.

Furthermore, the infrared single-photon counter ID230 has a simple USB interface allowing its users to set the efficiency, the temperature of the avalanche photodiode and the deadtime. Therefore, the features of the single-photon detector ID230 can be efficiently used in a number of applications such as Quantum Optics & Quantum Cryptography, Fiber Optics Measurement and other.
