The Spectra-CT LED-based uniform light sources provide adjustable luminance of up to 50,000 cd/m2 over exit ports of 5, 10 or 20cm with a continuously adjustable CCT of between 2800 & 7500K and a luminance uniformity of >98%. They are intended for the flat-field correction and radiometric calibration of image sensors & camera systems, as well as the photometric calibration of luminance meters.
Applications:
Mainly used for camera calibration and characterization such as flat field correction, linearity calibration, dark correction in the areas of:
