Examination of Minerals in Cross Polars

Examination of Minerals in Crossed Polars: When the analyzer is placed in the position with its plane of polarization at right angles to that of the polarizer, the polars are said to be ”crossed”. If a section of a doubly refracting mineral is placed between crossed polars, the light is doubly refracted and polarized three …

Polarizing Microscope

A polarizing Microscope is also known as the Polarized Light Microscope. The optical properties of minerals can be determined with the help of a Polarizing Microscope. In order to study minerals under a polarizing microscope, their thin sections of about 0.035 mm thickness are placed on the rotating stage of the microscope and examined. Main …

Optical Properties of Minerals

The optical properties of minerals are important for their identification. Optical properties are determined with the help of a ”polarizing microscope”. The study of optical properties of minerals is known as Optical Mineralogy. With the help of optical mineralogy, we study the minerals and rocks with the help of their optical properties. The rocks and …
