Fluorescent Material ColoriMeter

A fluorescence colorimeter irradiates the sample with multi-angle light sources, measures the wavelength and intensity of visible light emitted by the fluorescent material under excitation, and calculates the chromaticity coordinates and color difference values. It is used to detect color consistency in materials such as fluorescent coatings and inks, and to control color variations across production batches.
Selection
When selecting, consider matching the sample's fluorescence intensity with the instrument's measurement range. The configuration should include a light source system covering the ultraviolet spectrum, ensure the measurement aperture is suitable for the sample's shape, and the software must support fluorescence colorimetry calculations, with an operation interface that aligns with daily testing workflow requirements.
