Polarizing microscopy

The polarizing microscopy is a method of supervision in polarized light for microscopic research of the preparations including optically anisotropic elements (or entirely consisting of such elements). For example minerals, some animal and vegetative tissues Optical properties of anisotropic microobjects are various in various directions and are shown differently depending on orientation of these objects concerning a direction of supervision and a plane of polarization of light falling on them. Supervision can be spent both in passing, and in reflected light. Light radiated by the lighter, pass through a polarizer. The polarization received by this light varies at the subsequent passage of light through a preparation (or reflection from it). These changes are studied by means of the analyzer and various optical equalisers. The analysis of such changes gives the basic optical characteristics of anisotropic microobjects: force of double refraction, quantity of optical axes and their orientations, rotation of a plane of polarization, dichroism.
