Arc-shaped surface coloriMeter

The arc-shaped colorimeter uses a multi-angle annular light source to illuminate the sample and captures reflected light data from different angles through sensors to analyze color differences. It is used to measure color consistency on curved surfaces or special coatings such as metallic paint and pearlescent paint, controlling product appearance quality in industries such as automotive and home appliances.
Selection
When selecting, consider matching the curvature radius of the object being measured with the instrument's measurement aperture, confirm whether the number of multi-angle configurations and light source types supported by the instrument comply with industry standards, verify data on measurement repeatability and inter-instrument variability, and assess whether the software functionality meets the color control requirements of the production site.

Colorimeter controls batch color difference in plastic and rubber films.
This article primarily discusses how to use a colorimeter to control color differences in the production of plastic and rubber films. It explains the working principle of the colorimeter, which involves converting colors into numerical values represented by L, a, and b values, and then calculating the color difference.
Colorimeter evaluates the change in yellowing index of transparent resin.
This article introduces how to use a colorimeter to measure the yellowing index changes in transparent resin. Transparent resin can turn yellow over time or due to environmental influences, and the yellowing index can quantify the degree of color change.
Application of Colorimeters in Color Management for Packaging and Printing
This article mainly discusses the application of colorimeters in color management for packaging and printing. A colorimeter is an instrument used to measure color, capable of converting colors into numerical values, such as representing them with L*a*b* values.
Multi-angle colorimeter detects color changes in pearlescent coatings.
Pearlescent coatings contain special flake pigments that produce color effects that vary with the viewing angle, known as "goniochromism." Traditional single-angle measurements struggle to accurately capture this characteristic.
Application of Colorimeters in Controlling Color Differences in Paint Batches
This article introduces the role of colorimeters in controlling color consistency in paint production. Since human judgment of color is easily influenced by lighting and subjective factors, colorimeters quantify color differences in the CIELAB color space by measuring spectral data, providing an objective basis for production.
Application of Colorimeter and Color Matching Box in Pigment Color Inspection
A colorimeter and a light booth are two primary tools in pigment color inspection. The colorimeter measures color through photoelectric principles, while the light booth provides a standardized light source environment for visual evaluation of color effects, metamerism, and other phenomena.
