Basic principle and main application of polarizing microscope
Polarizing microscope (English name: Polarizing microscope) is a method of changing ordinary light into polarized light for microscope inspection to identify whether a substance is single refraction (isotropy) or birefringence (anisotropy). In addition, birefringence is a basic characteristic of crystals, so it involves many fields.
Basic principle of polarizing microscope:
Polarizing microscope is a kind of microscope to identify the optical properties of the fine structure of matter. With the development of science and technology, polarizing microscope technology is constantly improving. Any substance with birefringence can be clearly distinguished under a polarizing microscope. Therefore, a polarizing microscope is currently the most effective tool for studying the crystal phase microstructure of materials. one.
The main purpose of polarizing microscope:
(1.) Medical analysis
Polarizing microscopes are also used in medicine. For example, medical staff can use them in arthritis, uric acid crystals, and stone detection.
(2.) Biological field
Polarizing microscopes are also used in the biological field. Using polarizing microscopes, detailed studies can be performed to observe spinning filaments, collagen, etc. during cell division.
(3.) Identification of various biological and non-biological materials: such as fiber, drug component identification, liquid crystal, DNA crystal, etc.
(4.) Geological and mineral analysis
Polarizing microscopes have a wide range of applications, and can also be used for polarized light detection of various minerals and crystals, and are widely used in petroleum, mining and semiconductor industries. Under a polarizing microscope, it can be used for identification and observation of transparent minerals, as well as analysis of thin sections of rock minerals, identification and observation of thin sections of igneous rocks, sedimentary rocks, metamorphic rocks, etc., or LED lighting and special filters can be used in quality control and industrial analysis.
