Refractive index and gloss

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. So, for example, there’s a big difference between light ... WebNOTE: Gloss and Sheen are measured by a glossmeter. The values expressed in Gloss Units (GU), and are based on a highly polished reference black glass standard with a defined refractive index having a specular reflectance of 100GU at the specified angle. 0 GU being perfectly matte and 100 GU being perfectly ‘mirror-like’.
