principal piece of equipment used by the geologists to observe the optical properties of minerals. It has indispensable applications for Petrography, Crystallography, Geology, Mineralogy, Ceramics, Toxicology, Chemical Microscopy or detecting defects in semiconductors or finding stress points in metal, glass, textiles, etc. It permits orthoscopically or conoscopically to examine and identify the structures and characteristic of material with highly resolved distinctive images under various magnifications.
