Colorimeters

Colorimeters (9)

Colorimeters and spectrophotometers are optical devices for measuring color, enable the measurement of color difference between the model and the test sample. Colorimeters and spectrophotometers are used for quality control inter alia in the plastics industry, garment industry, printing, production of furniture and upholstery, and many others.

All our models show the difference between the model and the test sample. The difference is based on measuring the difference between the hue, saturation, and brightness (given as: E * ab; ΔL * ab; E * C * H, where ΔE is the total color difference, ΔL-the difference in brightness, Δa- difference on the red-green axis, Δb- difference on a yellow-blue axis, ΔC- difference saturation, ΔH-difference hue).

The color of objects formed by the action of radiation reflected on the eye or passed through these items. Color assessment can be made on the basis of its color scale so that it is possible to describe the numerical value. Systems (spaces) allow you to specify colors and color analysis and calculation of the differences between the two colors.

The most well-known and recommended by the CIE (Comission Internationale de l'Eclairage - International Commission of Illumination) system is the CIE Lab color. CIE Lab space is based on the so-called tristimulus model of color perception and was established to allow the color designation in the system three rectangular coordinates L * a * b. In addition to the analysis of the color difference is used coordinate system angular L * C * h °. The total color difference should be based on an analysis of all of the aforementioned values components.
