Spectrophotometric Color Luminance Meter

The spectral colorimeter measures the intensity of reflected light at various wavelengths from an object's surface through a spectroscopic system, and calculates brightness and chromaticity values by combining standard light sources with colorimetric formulas. It is used for color difference monitoring in printed materials, color calibration of coatings, and color calibration of display screens, ensuring objective and comparable color data.
Selection
When selecting, focus on ensuring that the measurement geometry matches the actual observation angle, the spectral resolution meets industry standards, and the probe size is suitable for the area being measured. Consider the instrument's repeatability index and compatibility with existing color management systems. Environmental light shielding design and long-term stability also need to be verified.
