Xenics (Leuven, Belgium) offers the Cheetah-640-CL SWIR camera. The new 800-Hz version outputs 12-bit images via a standard CameraLink medium interface. A TE1-cooled sensor allows the Cheetah-640-CL to achieve low dark current characteristics from 1 μs up to 40 ms @ 25°C sensor temperature (high gain mode), or up to 100 ms @ 268K sensor temperature (high gain mode). The camera obtains above 1000 frames per second at 640×512 resolution. The device is currently being used in adaptive optics systems to correct imaging systems for atmosphere turbulence.
