C-RED One is a ultra high-speed photon counting SWIR camera using MCT e-APD array with 24 μm pixel pitch. The sensor allows sub-electron readout noise, taking advantage of the e-APD noise free multiplication gain and non-destructive readout ability. he discovery of electron initiated avalanche photodiodes (e-APD) using mercury cadmium telluride (MCT) semiconductor materials permitted a significant breakthrough in SWIR imaging. C-RED One uses a unique 320 x 256 pixels MCT e- APD array with 24 μm pixel pitch with a wide spectral response over J, H and K bands, and outstanding cosmetics. The sensor delivers unprecedented sub-electron readout noise, taking advantage of the e-APD noise free multiplication gain and non-destructive readout ability. C-RED One is capable of capturing up to 3500 full frames per second, without compromising on subelectron readout noise or very low background. The camera can also capture multiple regions of interest (ROI) readout allowing faster image rate (10’s of KHz) while maintaining sub-electron readout noise. C-RED One offers multiple readout modes: Global reset: Single read, Correlated Double Sampling (CDS), multiple non-destructive readouts (NDR) including ramp up and Fowler modes Rolling Reset: Single, N readout and IOTA including Ramp up and Fowler modes C-RED One is an autonomous system: the sensor is placed in a sealed vacuum environment and cooled down to cryogenic temperature (90 K) using an integrated pulse tube with a high reliability. The vacuum regeneration is managed by the camera.
