Variable-angle PhotoMeter

A variable-angle photometer measures the intensity of reflected or transmitted light at different angles by varying the angle between the incident light and the sample. It is used to analyze the gloss and color characteristics of material surfaces as they change with angle, commonly employed in quality inspection for coatings, plastics, and printed materials.
Selection
When selecting, consider whether the measurement angle range covers the requirements, sample size compatibility, instrument repeatability data, ability to handle ambient light interference, adaptability of the operation interface, and whether maintenance costs and calibration cycles match the actual usage conditions.
