What is a Spectrophotometer?

A spectrophotometer is a device that digitizes colors. Although it is possible to judge colors with the human eye, it is not possible to make an accurate judgment because it is a qualitative evaluation and the appearance of colors differs from person to person.
On the other hand, the color of a product is often one of the items for quality evaluation. Therefore, a spectrophotometer numerically evaluates colors by quantifying the brightness and the intensity of each color such as red, blue, and green. In addition, since the appearance of colors changes depending on how the light hits, the distance and intensity from the light source are also recorded when measuring with a spectrophotometer.

Application of Spectrophotometer

Spectrophotometers are used in color-related industries such as design, tint, and paint. Since the spectrophotometer is a measuring device related to color, it is used in various genres. For example, in the automobile industry, the design and color of a car are important, so a Spectrophotometer is sometimes used for quality inspection of the car body after painting. Also in the paint industry, colorimetric evaluation is performed using a Spectrophotometer to create a paint that shows the desired color.
Spectrophotometers are also used as one of quality control In addition, in industries such as the food industry and design industry where the appearance of products is important, color evaluation using a Spectrophotometer is performed as one of the quality control methods.
