Spectrophotometric Color Comparator

A spectrophotometer analyzes color characteristics by illuminating a sample with a light source and measuring the intensity of light absorption or reflection at different wavelengths. It is used in industries such as coatings and plastics to test product color consistency and control production quality.
Selection
When selecting a spectrophotometer, it is essential to consider matching the measurement aperture to the sample size, opting for an integrating sphere structure to accommodate surface texture, ensuring the wavelength range covers application requirements, paying attention to instrument repeatability and inter-instrument agreement, and ensuring compatibility with existing color management systems.
