Aurea Technology is launching this month its newly-designed SPD_AT, its first all-in-one high-performance near infrared time-resolved single photon counting module for Time Correlated Single Photon Counting (TCSPC) applications.

The SPD_AT is an ultra-low-noise, high quantum efficiency and low timing jitter near infrared (900 – 1700nm) single photon counter with 50ps timing correlation feature. The SPD_AT includes a Geiger-mode InGaAs avalanche photodiode and thermoelectric coolers that ensure high detection efficiency up to 25 per cent, a very low dark count rate <5.10-6 per ns gate, and a low timing jitter of <180ps.

The SPD_AT is a very compact all-in-one TCSPC single photon counter. It comes with its easy-to-use and ergonomic GUI compatible with LabView and C++.

A dual version, the SDP_AT_M2, with two photon detectors is also available. The SPD_AT time-resolved single photon counter family is suitable for use in fluorescence lifetime, photoluminescence, spectroscopy and time correlated single photon counting applications.
