Color Matching


Using Color As Light Source for 3D Scanning.

Under different light conditions, colors will look differently. The best color appearance will always be under sunlight, because there will be the full spectrum of light, as well as the right brightness. Color temperature is a characteristic of visible light that has important applications in lighting, photography, videography, publishing, manufacturing, astrophysics, horticulture, and other fields. The color temperature of a light source is the temperature of an ideal black body radiator that radiates light of comparable due to that of the light source.

Learn how to capitalize on color matching as an alternative scanning method.

Color Matching for Quality Purpose.

Daylight conditions can be simulated with our Color Matching Systems. To achieve this, ColorControlOptics (CCO) are activated using digital signals resulting in an optimum setting of the inspection light.

Depending on the sample under inspection, the most reflected wavelengths hereby are reduced to light waves which are used for illumination. This results in clear visualization of color differences which are normally superimposed. As a result, color flaws and color differences between work pieces or materials become clearly visible.

Color Temperature as Light Source.

In practice, color temperature is only meaningful for light sources that do in fact correspond somewhat closely to the radiation of some black body, i.e. those on a line from reddish/orange via yellow and more or less white to blueish white. Color temperature is conventionally stated in the unit of absolute temperature, the kelvin, having the unit symbol K.

Color temperatures over 5,000K are called cool colors (blueish white), while lower color temperatures (2,700–3,000 K) are called warm colors (yellowish white through red).
