Polarising microscope features Polarising microscope uses

Polarising microscope is a kind of microscope used to study the so-called transparent and opaque anisotropic materials, which has important applications in geology and other science and technology professions. Any substance with birefringence can be distinguished clearly under a polarising microscope, of course, these substances can also be observed by staining, but some of them can not be used and must be observed using a polarising microscope. Reflective polarizing microscope is a necessary instrument for the research and identification of birefringent substances by using the polarising property of light, and it can be used for single polarization observation, orthogonal polarization observation and cone light observation by the majority of users.

Features

It is a method to change ordinary light into polarised light for microscopic examination to identify whether a substance is monorefractive (isotropic) or birefractive (anisotropic). Birefringence is a fundamental property of crystals. As a result, polarising microscopy is widely used in the fields of minerals and chemistry, as well as in biology and botany.

Polarising microscopy is a type of microscope that identifies the optical properties of the fine structure of a substance. Any substance with birefringence can be distinguished clearly under the polarising microscope, of course, these substances can also be used for observation by staining, but some of them are not possible, and polarising microscope must be used.

The characteristic of polarising microscope is to change ordinary light into polarised light for microscopic examination, in order to identify a substance as monorefractive (isotropic) or birefractive (anisotropic).

Birefringence is a fundamental characteristic of crystals. As a result, polarising microscopy is widely used in minerals, polymers, fibres, glass, semiconductors, chemistry and other fields. In biology, many structures are also birefringent, which requires the use of polarising microscopes to distinguish them. In botany, such as identifying fibres, chromosomes, spindle filaments, starch grains, cell walls and the presence of crystals in the cytoplasm and tissues. In plant pathology, the invasion of pathogens often causes changes in the chemical properties of tissues, which can be identified by polarising microscopy.

Uses

Polarising microscope is an important instrument for the study of optical properties of crystals, and at the same time, it is the basis of other crystal optical research methods (oil immersion method, Fuchs' table method, etc.).

Polarizing microscope is a necessary instrument for the research and identification of birefringent substances by using the characteristic of light polarisation, and it can be used for single-polarized light observation, orthogonal polarized light observation and cone light observation. It is a method to change ordinary light into polarised light for microscopic examination, in order to identify whether a substance is monorefractive (isotropic) or birefractive (anisotropic).

Birefringence is a fundamental characteristic of crystals. Therefore, polarising microscopes are widely used in the fields of minerals and chemistry. In human body and zoology, polarized light microscopy is often used to identify bones, teeth, cholesterol, nerve fibres, tumour cells, rhabdomyosarcoma and hair. Today, we introduce about the application areas of polarising microscope.
