Introduction of the principle of gloss meter:
First: The manufacturer of the Stone gloss meter tells you that gloss is a physical quantity that evaluates the ability of the surface of a material to reflect light under a set of geometrically specified conditions, and has a direction-selective reflection property.

Stone gloss meter manufacturers tell you that the gloss we usually say refers to "mirror gloss", so the gloss meter is sometimes called "mirror gloss meter". Stone gloss meter manufacturers tell you that gloss is completely different from the concept of "finishness" or "roughness" in the machining industry, which is a continuation of the tiny unevenness on the surface of a material.

Second: The manufacturer of the Stone gloss meter tells you that the measuring head of the gloss meter is composed of an emitter and a receiver. The emitter is composed of an incandescent light source and a set of lenses, which generate a certain required incident beam. The manufacturer of the Stone gloss meter tells you that the receiver consists of a lens and a photosensitive element to receive the cone of light reflected from the surface of the sample, and mirror gloss is a relative measure of mirror gloss.

The above information is Stone gloss meter manufacturers' introduction and analysis of the principle of gloss meter, hope it helps you.
