Spectrophotometry is a method of measuring the color of an object by analyzing the spectrum of light. It is a very accurate color measurement method that measures color information across the entire visible spectrum.
In spectrophotometry, a spectrometer is used to analyze the light reflected or transmitted by an object. Spectrometers break down light into its spectral components at different wavelengths and measure the intensity of light at each wavelength. By analyzing the light intensity at each wavelength, the spectral distribution of an object can be calculated and its color determined.
Compared with other color measurement methods, spectrophotometric colorimetry can provide more detailed color information, because it can not only measure the color coordinates of objects, but also measure parameters such as color, chroma, hue, and brightness of objects. more accurate and comprehensive evaluations. Spectrophotometric colorimetry is widely used in color-related industries and fields such as pigments, plastics, coatings, textiles, and food.
