The measuring principle of the gloss meter:
1. Gloss is the physical quantity that evaluates the ability of a material to reflect light at a set of geometrically specified conditions. Therefore, it expresses the reflective properties with direction selection. According to the characteristics of the gloss, the gloss can be divided into several categories. The gloss that we usually say refers to the "mirror of the mirror", so the gloss meter, sometimes called the mirror gloss meter. Gloss is completely different from the “finish†or “roughness†of the machining industry, which is a measure of the small unevenness of the material surface.
2. The light source emits a beam of light through the lens L1 to reach the measured surface P, and the measured surface P reflects the light to the lens L2. The lens L2 concentrates the light beam to the photocell located at the light column B, and the photoelectric signal is converted by the photoelectric battery. The processing circuit is processed, and then the gloss meter displays the measurement results.
