AUREA Technology (Besancon, France) has introduced the SPD_B, a single-photon counting module used for short near infrared wavelengths [1,000 to 1,350 nm]. The SPD_B is an ultra-low-noise, highquantum- efficiency, and low-timing-jitter near-infrared single photon counter. The SPD_B includes a Geiger-mode InGaAs avalanche photodiode and thermoelectric coolers that ensure high detection efficiency up to 30%, a very low dark count rate of < 5.10-6 per ns gate, and a low timing jitter of < 180ps. The SPD_B comes with a graphical user interface compatible with LabView and C++.
