WebSummary. Optical properties are a striking expression of the anisotropic internal structure of minerals. The best way to convince yourself that this is true is to examine a thin section of a rock (a 20–30 μm thick slice, see Chapter 10) in a petrographic microscope with polarized light and compare the effects with those from a plain glass slide. WebOptical Properties 2.3.1. Reflectivity Reflectivity is defined as the ratio of the intensity of the light reflected by a mineral to the intensity of the light incident upon it, expressed in percent with a variation from below 10% to nearly 100% in opaque substances.
