The SQLightSensor Is an Ultra Low Noise Near Infrared Single Photon Detector Based on a Geiger-Mode InGaAs Avalanche Photodiode and an Internal Thermoelectrically Cooler
The SQLightSensor includes a Geiger-mode InGaAs avalanche photodiode (APD) and a thermoelectrically cooler (TEC) that ensures high detection efficiency up to 25%, low dark count (5.10-6 per ns gate), high speed trigger up to 10 MHz, and low jitter. The gate width and the delay are adjustable. Thanks to its outstanding high level detection sensitivity the SQLightSensor provides significant benefit over existing detectors.
In addition the SQLighSensor provides plug-and-play Personal Computer connections via the USB interface which enable to easily adjust the detection efficiency, and tune the gate width and delay.
The SmartQuantum's Single Photon Detector SQLightSensor is ideal for the most demanding scientific, defense and industrial applications, such as single photon counting, spectroscopy, microscopy, fluorescence, eye-safe laser range finder and LIDAR, and quantum cryptography.

To order the photodetectors
I want to know the Characteristics of the photodetectors, wavelenth,responsivity,frequency bandwidth, and so on, but I fail to find it.
