The discovery of electron-initiated avalanche photodiodes (e-APD) using mercury-cadmium-telluride (MCT) semiconductor materials enabled a major breakthrough in SWIR imaging.
C-RED One uses a unique 320 x 256 pixel HgCdTe e-APD array with a pixel pitch of 24 µm. The sensor enables sub-electron readout noise and uses the noise-free multiplication gain of the e-APD and the non-destructive readout capability. The system is able to read out several regions of interest (ROI). This enables a faster frame rate (10 KHz) with unprecedented sub-electron readout noise. The sensor is cooled down to a cryogenic temperature (80 K) via an integrated and reliable pulse tube. Several readout modes (global reset, rolling reset, single read, CDS or non-destructive reads) are possible.
C-RED One opens up completely new possibilities in terms of sensitivity and speed in the field of scientific SWIR cameras.
