InGaAs free-running single-photon detector

This product is a compact near infrared free running single photon detector.
The core device adopts InGaAs/lnP with domestic independent intellectual property rights
Compared with similar products, APD has advanced technical indicators, reliability and integration, and can be used for asynchronous low light detection such as liDAR and fluorescence lifetime detection
Applications provide cost-effective solutions.
This product uses a negative feedback APD to achieve fast avalanche quenching and low electronic noise, high detection efficiency and low dark count by optimizing the electronics and thermal design. Among them, the maximum detector efficiency of 1550nm single photon is > 35%; At this time, the time jitter can be as low as 80ps; Detector efficiency
At 15%, the minimum dark count is 500 CPS, and the minimum post pulse is 1%@ dead time 5 um; Saturation counting rate up to 4MCps@ dead time 250nso
In addition, for specific application scenarios, support bias, screening threshold, dead time and other parameters of the user configuration function to strengthen the detection efficiency, saturation count rate and other specific indicators; Support time digital conversion (TDC) function can be determined
To obtain time counting data, support free running or external trigger gating
Two operating modes are available.
