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 […]
