The SPD_A is a new generation of all-in-one ultra-low-noise near infrared single photon counting modules ideal for the most demanding scientific and industrial applications. The SPD_A includes a Geigermode InGaAs avalanche photodiode (APD) and a thermoelectrically cooler that ensure high detection efficiency up to 25%, very low dark count, and low timing jitter. Thanks to its outstanding high level detection sensitivity and speed the SPD_A provides superior performances over existing detector technologies, such as NIR Photomultipliers and Micro Channel Plates. In addition to its ergonomic display, the SPD_A provides plug-and-play Personal Computer connection via its USB interface and easy-to-use Graphical User Interface, which enables you to easily adjust the photon detection efficiency, the dead time and tune the gate width. The SPD_A is the most sensitive, compact and easy-to-use single photon counting module in today’s market.
