Gloss, as the surface characteristic of an object, depends on the specular reflection ability of the surface to light. The so-called specular reflection refers to a reflection phenomenon where the reflection angle is equal to the incident angle. Glossiness is a physical quantity that evaluates the ability of the surface of a material to reflect light under a set of geometrically prescribed conditions. Therefore, it expresses the reflective properties of direction selection. So how much do you know about its measurement knowledge? Follow the editor of Best Sheen meter For sale to have a simple understanding!

Gloss measuring instrument is used to measure gloss. Most gloss measuring instruments measure the reflectance of the object surface, which is called specular gloss measuring instrument. The angle of incident angle selected during the measurement is different, and the measured result is also different. The greater the incident angle, the greater the specular reflectance and the higher the gloss, which is why the high gloss material should be measured with a high gloss measuring instrument at a 20 degree angle; on the contrary, the lower the specular reflectance, the lower the gloss. It is necessary to use a low gloss measuring instrument with an angle of 85 degrees. It can be seen that the gloss level not only depends on the surface characteristics of the object, but also depends on the measuring angle of the instrument.
