A polariscope uses polarized light for gem identification. It consists of two polarized filters, one on the top and one on the bottom of the instrument as seen in the picture to the right. Both the polarizer and the analyzer have their own vibrational planes.

The GIA Polariscope is used to test the optical properties of gemstones and determine whether a stone is singly refractive, doubly refractive or is an aggregate. Doubly refractive stones may be divided further as to whether they are uniaxial or biaxial.

The polariscope is used primarily to determine the optic character of transparent to translucent gem materials; in other words, it determines whether a stone is singly refractive (SR), doubly refractive (DR), or is an aggregate (AGG).

A polariscope is a qualitative tool that uses polarized light to reveal stress patterns in transparent or translucent objects. Strainoptics offers several standard models of polariscopes (strain viewers), ranging from a small, portable unit to large, modular instruments that may be free-standing, installed on a wall, on a tabletop, or even on a ...
