Hyperspectral CMOS Camera

Imec (Leuven, Belgium) is currently sampling the line scan version of its hyperspectral imaging solution, offering a ready-to-use evaluation kit to the industry to line scan and analyze specific sample material. Imec’s line scan solution monolithically integrates hyperspectral filters on a CMOSIS CMV4000 imager (4 megapixel, max 180 fps). It scans 100 spectral bands in the 600-1000nm wavelength range. The filter bandwidth (Full Width Half Max) is about 10nm across the spectral range, with a transmission efficiency of ~85%. The speed of the system corresponds to an equivalent speed of 2,000 lines per second.

Imec’s prototype hyperspectral imager for snapshot and video captures an entire multispectral image at one discrete point in time. The imager is achieved by applying a hyperspectral filter in a novel tiled lay-out on a commercially available CMOS-based image sensor (CMOSIS CMV2000, 2 megapixel, max 340 fps).
