Polarizing Microscope Features Polarizing Microscope Applications
Polarizing microscope is a kind of microscope used to study so-called transparent and opaque anisotropic materials, and has important applications in geology and other science and engineering majors. All substances with birefringence can be clearly distinguished under a polarizing microscope. Of course, these substances can also be observed by staining, but some of them cannot be used, and a polarizing microscope must be used. Reflective polarizing microscope is an essential instrument for the research and identification of birefringent substances by using the polarization characteristics of light. It can be used for single polarized light observation, orthogonal polarized light observation, and conoscopic light observation.
features
A method of changing ordinary light into polarized light for microscope inspection to identify whether a substance is single refraction (isotropy) or birefringence (anisotropy). Birefringence is a fundamental property of crystals. Therefore, polarizing microscopes are widely used in mineralogy, chemistry and other fields, as well as in biology and botany.
Polarizing microscopy is a microscope for identifying the optical properties of the fine structure of matter. All substances with birefringence can be clearly distinguished under a polarizing microscope. Of course, these substances can also be observed by staining, but some of them are impossible, and a polarizing microscope must be used.
The characteristic of polarizing microscope is the method of changing ordinary light into polarized light for microscope inspection to identify whether a substance is single refraction (isotropy) or birefringence (anisotropy).
Birefringence is a fundamental characteristic of crystals. Therefore, polarizing microscopes are widely used in fields such as minerals, polymers, fibers, glass, semiconductors, and chemistry. In biology, many structures also have birefringence, which needs to be distinguished by polarizing microscopy. In botany, such as identifying fibers, chromosomes, spindle filaments, starch grains, cell walls, and whether crystals are contained in cytoplasm and tissues. In plant pathology, the invasion of pathogens often causes changes in the chemical properties of tissues, which can be identified by polarizing microscopy.
use
Polarizing microscope is an important instrument for studying the optical properties of crystals, and it is also the basis of other crystal optical research methods (oil immersion method, Freund's method, etc.).

Birefringence is a fundamental characteristic of crystals. Therefore, polarizing microscopes are widely used in mineral, chemical and other fields. In human and zoology, polarized light microscopy is often used to identify bones, teeth, cholesterol, nerve fibers, tumor cells, striated muscles, and hair. Today, I will introduce the application fields of polarizing microscopes.
1. Biological field: In organisms, different fibrin structures show obvious anisotropy, and the details of the molecular arrangement in these fibers can be obtained by using a polarizing microscope. Such as collagen, spinning silk during cell division, etc.
2. Identification of various biological and non-biological materials: such as starch property identification, pharmaceutical composition identification, fiber, liquid crystal, DNA crystal, etc.
3. Medical analysis: such as stones, uric acid crystal detection, arthritis, etc.
4. Geological and mineral analysis:
In addition to common biomedical applications, polarizing microscopes can also be used for polarized light detection of various minerals and crystals, and are widely used in petroleum, mining and semiconductor industries. LED lighting and special filters can be applied in quality control and industrial analysis.
