Kiillottavuus

Kiillottavuus refers to the ability of a surface to reflect light in a specular or mirror-like manner. It is a property that describes how smoothly a material's surface is finished. A highly polished surface will exhibit a high degree of kiillottavuus, meaning it will reflect light rays in a parallel fashion, creating a clear image. Conversely, a rough or unpolished surface has low kiillottavuus and scatters light diffusely, resulting in a dull appearance.

The degree of kiillottavuus is influenced by the microscopic topography of the surface. Smoothness is achieved through processes like grinding, lapping, and polishing, which reduce the presence of irregularities, scratches, and imperfections. Materials like metals, glass, and certain plastics can achieve high levels of kiillottavuus when properly finished. The concept is important in various fields, including optics, where lenses and mirrors require precise surfaces for accurate light manipulation, and in manufacturing, where the aesthetic appeal and functionality of products often depend on a polished finish. Measuring kiillottavuus can be done using instruments that assess the intensity and direction of reflected light.
