Spectral Luminance Measurement Meter

A spectrophotometer calculates chromaticity coordinates and brightness values by measuring the spectral distribution of light reflected from an object's surface. It is used for color quality control in industries such as coatings and plastics, enabling the detection of color differences and changes in glossiness.
Selection
When selecting, consider matching the measurement aperture to the sample size, choose models that include the required color standard system, confirm data consistency between instruments, select flat or curved measurement attachments based on the sample shape, and check calibration cycles and maintenance requirements.
