Crystals are grouped by their optical sign. When the refractive index is greater than the refractive index the crystal is said to have a negative optical sign. Calcite is an optically negative crystal. 14. One of the images is less distinct than the other. This indicates that the light that travels along this path is absorbed

WebOptical 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.
