As a photoelectric device, the color matching light box can simulate different standard artificial light sources to ensure that the product has a color matching environment close to natural light. Different brands and specifications of color matching light boxes have different types of light sources, but they are often equipped with several common light sources. This article introduces the types and functions of common light sources for color matching light boxes.

Colorimeter is an optical analysis instrument developed based on colorimetry. Therefore, various colorimetric parameters are involved in the process of color measurement, among which the common ones are: 45/0 and d/8, SCI and SCE, 2° and 10°, L*a*b* and Lab, XYZ and Yxy. Initial users are generally not very clear about these similar parameters, which are introduced below.

The CIELab and CIELCh modes of colorimeter are two commonly used colorimetric models in colorimeter. The CIELab model is the most commonly used color measurement model of colorimeter, while the CIELCh mode is a model derived from CIELab. There is a certain relationship between the two. This article introduces the meaning of the color difference values of the CIELab and CIELCh modes of colorimeter?

The integrating sphere is an important component of the colorimeter, which largely determines the service life, measurement accuracy and long-term repeatability of the colorimeter. However, the integrating sphere is a consumable part, and various problems may occur during use . So, does the integrating sphere of the colorimeter need to be replaced? How to maintain it? This article introduces this.

CIELab and Hunter Lab are commonly used color measurement spaces for colorimeter. Both color spaces use the three parameters L, a, and b to express color, but their meanings are different. This article analyzes the difference between CIELab and Hunter Lab.

When working, the colorimeter generally relies on the CIELab color space, and outputs L, a, b values, and color difference values such as △L, △a, △b, △E after colorimetry by comparing the color difference values between the sample and the standard. This article introduces the range of L, a, b of the colorimeter and the meaning of Lab color difference values.
