InGaAs deep-cooled free-running single-photon detector Norge

This product is a 4-channel deep-cooling near-infrared free-running single-photon detector. Its core component features domestically developed and proprietary InGaAs/InP APD technology, offering advanced technical specifications, reliability, and integration compared to similar products. It provides a cost-effective solution for asynchronous weak-light detection applications such as laser radar and fluorescence lifetime measurement.
Utilizing a negative feedback APD, this product can be cooled to -110°C using thermoelectric cooling technology, significantly reducing dark count rates, which can be as low as 100ps. The maximum detection efficiency for 1550nm single photons exceeds 20%. Additionally, tailored to specific application scenarios, it supports user-configurable parameters such as bias voltage, discrimination threshold, and dead time to enhance detection efficiency and saturation count rates, among other specific metrics.
