What is a Polarizing microscope?

A polarizing microscope is a type of optical microscope. The optical microscope used in science experiments observes all the light reflected by the material through the eyepiece, while the polarizing microscope observes the light reflected from the material with anisotropy that vibrates in a specific direction. increase. Light with this anisotropy is called polarization, and when it hits a substance from various angles, it is possible to observe different colors and different light and darkness. By combining this with a microscope, it is possible to identify the state and composition of a substance.

Application of Polarizing microscope

Originally, it was a polarizing microscope that was used to know the state and composition of minerals, but its use is expanding to development sites such as polymers and biotechnology. One of the big discoveries using a polarizing microscope is the liquid crystal display. Liquid crystals, which are liquid but have a solid-like molecular arrangement, were first confirmed by observation with a polarizing microscope, which led to the development of today's liquid crystal televisions. In addition, many biological substances have the same state and molecular structure as liquid crystals, and we believe that polarizing microscopes will continue to play an active role in the fields of medicine and pharmaceuticals.
