Isotropic materials, which include gases, liquids, unstressed glasses and cubic crystals, demonstrate the same optical properties in all directions. They have only one refractive index and no restriction on the vibration direction of light passing through them. Anisotropic materials, in contrast, which include 90 percent of all solid substances, have optical properties that vary with the orientation of incident light with the crystallographic axes. Optical Properties of Minerals » Geology Science The petrographic microscope In order to use the scope, we need to understand a little about the physics of light, and then learn some tools and tricks… Thin section Thin rectangular slice of rock that light can pass through.

The Best Petrological Microscope For Students and Geologists The Best Petrological Microscope (Petrographic Microscope Reviews) A petrologist uses microscopes and chemical tests to determine the nature of rocks and minerals. Microscope examination of a rock specimen mounted on a thin section slide is the principle technique used to identify the rock specimen. Further study can determine the components and features of the rock along with its composition, how it was formed and the geological setting of the rock.
