Optical guided coloriMeter

The light guide colorimeter uses optical fibers to transmit light to illuminate the sample, receives the reflected light through sensors, and analyzes the spectral data to measure the color parameters of the object. It is used for color quality control in industries such as coatings and plastics to ensure color consistency across product batches.
Selection
When selecting a spectrophotometer, consider matching the measurement aperture to the sample size, ensuring instrument repeatability meets industry standards, and compatibility with existing color management systems. Evaluate environmental adaptability, opt for a robust structure to withstand workshop conditions, and ensure long-term stable performance.
