Small Aperture Surface Gloss Meter

The small-aperture curved surface gloss meter projects light onto a curved surface at a fixed angle, uses a small-aperture probe to capture the intensity of reflected light, and converts it into a gloss value. It is used to measure the specular reflection characteristics of curved or uneven surfaces, making it suitable for gloss quality control of curved products such as automotive parts and plastic casings.
Selection
When selecting, consider matching the measurement aperture size with the curvature of the surface, ensuring the reflection angle corresponds to the gloss range of the material being measured. Confirm that the instrument's calibration curve covers the actual gloss range of the sample. The probe material should be wear-resistant, and the device must have a surface curvature compensation function. Additionally, verify the validity of the calibration certificate issued by the metrology institution.

The use of a gloss meter in evaluating the surface gloss of printing paper and art paper.
Gloss meters quantify paper gloss by measuring surface reflected light, with 20°, 60°, and 85° angles commonly used for high, medium, and low gloss surfaces, respectively. The gloss characteristics of printing paper and art paper differ, so the appropriate measurement angle should be selected based on the estimated gloss level.
Determination of specular gloss: Selection criteria for instruments at different angles (20°/60°/85°)
Specular gloss is a measure of a material's ability to reflect light, calculated by comparing the reflected luminous flux of a sample with that of a standard plate. Three angles—20°, 60°, and 85°—are commonly used for measurement, corresponding to high-gloss, medium-gloss, and low-gloss surfaces, respectively.
