삼자극치 색도계와 분광 광도계는 모두 색차를 측정하는 데 사용됩니다., but their working principles and measurement methods are different.

Three stimulus value colorimeter by measuring the reflection or transmission of red, 녹색, blue three basic colors of light, calculate the sample of three stimulus values (엘, ㅏ, b value), so as to obtain the color difference between the sample and the standard color value. Tristimulus value colorimeter can measure the color brightness, chromaticity and hue of the sample. It is a commonly used portable colorimeter, which is suitable for some simple colorimetry.

삼자극치 색도계와 분광 광도계의 차이점은 무엇입니까?

Spectrophotometer uses spectrophotometry, by decomposing the light into different wavelengths of the spectrum, and then measuring the intensity of each wavelength of the light, 샘플의 스펙트럼 반사율 또는 투과율을 계산합니다., and then get the chromaticity coordinates and color difference value of the sample. Spectrophotometer can measure the spectral information of the sample, the measurement of color details is more accurate and fine, suitable for precision color measurement and color matching and other fields.

그러므로, the tristimulus value colorimeter is suitable for some simple color measurements, while the spectrophotometer is suitable for more complex and precise color measurements. The price of tristimulus colorimeter and spectrophotometer also varies, with tristimulus colorimeter usually having a lower price and spectrophotometer having a higher price. 적용 측면에서, tristimulus colorimeter is usually used for some simple color comparison and measurement, 예를 들어 서로 다른 배치의 색상이 일관된지 여부를 비교합니다., 제품이 색상 요구 사항을 충족하는지 판단, 등. The spectrophotometer is suitable for the field of fine color measurement and matching, 인쇄와 같은, 코팅, 높은 색상 정확도가 요구되는 섬유 및 기타 산업.

요컨대, tristimulus value colorimeter and spectrophotometer are different in color measurement, and the selection of the appropriate instrument needs to be determined according to the specific measurement requirements and application scenarios.
