From Nikon. 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.

A petrographic microscope is used to observe a series of characteristics in a mineral which reflect its properties and allow us to identify it. The petrographic microscope is a compound microscope which can work with plane polarised light, meaning that it has some peculiarities. Petrographic Microscope. Also known as a polarizing microscope, a petrographic light, is a compound microscope that uses polarized light for the purposes of analyzing and identifying rocks and minerals. Using this technique, it's possible to identify such characteristics as the texture and features associated with given minerals and rocks, etc Petrography is a branch of petrology that focuses on detailed descriptions of rocks. Someone who studies petrography is called a petrographer. The mineral content and the textural relationships within the rock are described in detail.
