Spectral Image Luminance Meter

A spectral image luminance meter measures the intensity of reflected light at various wavelengths from an object's surface through a spectroscopic system and combines imaging technology to obtain spatial luminance distribution. It is used to detect material color consistency, printing dot density, and coating uniformity, as well as to locate areas of color deviation defects in quality inspection.
Selection
When selecting, match the sample size with the instrument's field of view, determine the spectral resolution based on detection accuracy, and consider the need for ambient light shielding. Verify that the measurement speed aligns with the production line cycle, confirm that the software can output the required colorimetric indicators, and evaluate the equipment's resistance to vibration and dust protection capabilities.
