About
C-RED One is an ultra high-speed photon counting SWIR camera using a unique 320 x 256 pixels MCT e-APD array with 24 micrometre pixel pitch. The sensor allows sub-electron readout noise, taking advantage of the e-APD noise free multiplication gain and non-destructive readout ability.
The 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 micrometre pixel pitch, with a wide spectral response over J, H and K bands, and outstanding cosmetics.
C-RED One is capable of capturing up to 3500 full frames per second, without compromising on sub-electron readout noise or very low background. The camera can also capture multiple regions of interest (ROI) readout allowing faster image rate (tens of kHz) while maintaining sub-electron readout noise.
C-RED One is an autonomous system: the sensor is placed in a sealed vacuum environment and cooled down to cryogenic temperature (80 K) using an integrated pulse tube with high reliability. The vacuum regeneration is managed by the camera. A vibration control system option is available.
