Description

Spectrophotometer for continuous online colour measurement Range of Application Colour measurement based on the standard CIELab or ICUMSA- standard. Continuous online measurement of colours. Colour measurement of products with smooth and planar surfaces, no abrasive or bulk material. Guideline The CIELab-System is a colour space, which was specified by the International Commission on Illumination CIE (Commission Internationale d'Eclairage) in the year 1976. It was further derived from the CIE colour system and is based on the CIE “master” space which was introduced in the year 1931. CIELab system is today the most common colour system. On the basis of this equipment independent 3D-colour model, colour differences can be identified numerically. The model is impartial and complies nearly the human perceptiveness, by adapting the geometrical distance between two colours in the colour space with the human perception. The measured spectral curves will be reduces on three coordinates. The axes of the coordinates are positioned rectangular on each other: L* ,the light intensity, from 0 = absolute black to 100 = absolute white. a* describes the red - green axis. Negative values are green, the positives are red. b* describes the yellow - blue axis. Negative values are blue, the positives are yellow. Therewith the colour can be accurately described in the colour space. The calculation is effected under consideration of a standard light and an ordinary observer, that is, the colour values are calculated under defined physical conditions.
