Large-aperture coloriMeter

Large-aperture colorimeters measure the spectral composition of light reflected from an object's surface to calculate chromaticity coordinates and color difference values. They are used to detect color consistency across large or curved samples and monitor color stability between production batches in industries such as coatings and plastics.
Selection
When selecting, consider that the measurement aperture must cover the characteristic area of the sample, match the industry-standard color space, review the instrument's repeatability data, confirm portability or online installation requirements, evaluate the ambient light compensation function, and verify that the software's data export format is compatible with existing workflows.
