Cheetah 640 - InGaAs Camera for Low Light Level Imaging

The Cheetah-640CL TE3 camera is a high resolution, compact infrared camera, equipped with a dedicated low noise InGaAs detector array working from 0.9 μm up to 1.7 μm.

With its TE3 cooled sensor and water-cooled camerahead, the Cheetah-640CL TE3 is a highly sensitive camera achieving ultra low dark current at long integration times. It offers you an excellent measurement tool to image low light levels in the SWIR range such as for semiconductor failure analysis or for luminescence spectroscopy applications.

The Cheetah-640CL TE3 is delivered with a software development kit which offers direct access to various camera settings and allows easy integration with your own CameraLink image grabbing system.
