A specular reflection or gloss is what you get from a polished surface or mirror. It is clear, and you can see "through" the mirror. A diffuse reflection is what you get from a white wall. The light is bounced off it, but...
See MoreMeasurement angle refers to the angle between the incident light on a surface and the line perpendicular to the surface at the point of incidence. In specular reflection the incident and reflected angle are...
See MoreThere are no distinct differences in gloss units for the human eye to point out between the two samples.
The detectable differences depend on the gloss level of the sample e.g. 3.0 GU difference measured on a very matte...
Gloss is the optical property of a surface to reflect light into the specular direction, an important appearance factor. The visual impression of gloss is dependent on the individual perception, therefore...
See MoreA glossmeter is a precision measurement instrument. In order to determine the gloss of a surface, the glossmeter projects a beam of light at a fixed intensity and angle onto a surface and measures the amount of reflected...
