Spectra-CT Colour Tunable Uniform Light Source

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.



Mainly used for camera calibration and  characterization such as flat field correction,  linearity calibration, dark correction in the areas of:

  • Display panel inspection cameras
  • In-vehicle cameras
  • Cameras and ambient light sensors in  consumer electronics
  • Luminance meter and colorimeter response correction
