WebBecause gloss is really just a more familiar word for some rather intricate physics. Let’s start with the refractive index. It’s a bit complex, but one of the things it does is describe how fast light travels through a particular material and how much light reflects off its surface. Web1. jan 1978 · In this paper, a black tile Nvith a refractive index of 1.523 was used. The gloss (G) of a film is then defined as follows: G = Rs X 100 (4) g Since specular reflectance is a function of the angle of illumination, gloss is measured at a known angle. The choice of angle depends upon what standard one wants to use and the gloss of the film.

WebSome typical refractive indices for yellow light (wavelength equal to 589 nanometres [10 −9 metre]) are the following: air, 1.0003; water, 1.333; crown glass, 1.517; dense flint glass, … WebGloss is measured by an instrument called a glossmeter which assigns a gloss unit (GU) to a specified surface. The GU scale of a glossmeter is based on a highly polished, reference …

The glossmeter provides a quantifiable way of measuring gloss intensity ensuring consistency of measurement by defining the precise illumination and viewing conditions. The configuration of both illumination source and observation reception angles allows measurement over a small range of the overall reflection angle. The measurement results of a glossmeter are related to the amount of reflected light from a black glass standard with a defined refractive index. The ratio o…
