Characteristics of polarizing microscope Application of polarizing microscope
Polarizing 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 engineering majors. All substances with birefringence can be clearly distinguished under a polarizing microscope. Of course, these substances can also be observed by dyeing, but some are not, and a polarizing microscope must be used. Reflective polarizing microscope is an essential instrument to study and identify substances with birefringence by using the polarization characteristics of light, which can be used for users to observe single polarization, orthogonal polarization and cone light.
characteristic
A method of changing ordinary light into polarized light for microscopic examination to identify whether a substance is single refraction (isotropic) or birefringence (anisotropic). Birefringence is the basic characteristic of crystals. Therefore, polarizing microscope is widely used in minerals, chemistry and other fields, as well as in biology and botany.
Polarizing microscope is a microscope to identify the optical properties of fine structures of substances. All substances with birefringence can be clearly distinguished under a polarizing microscope. Of course, these substances can also be observed by dyeing, but some are impossible, and a polarizing microscope must be used.
The characteristic of polarizing microscope is to change ordinary light into polarized light for microscopic examination, so as to identify whether a substance is single refractive (isotropic) or birefringent (anisotropic).
Birefringence is the basic characteristic of crystals. Therefore, polarizing microscope is widely used in mineral, polymer, fiber, glass, semiconductor, chemistry and other fields. In biology, many structures are also birefringent, which needs to be distinguished by polarizing microscope. In botany, such as identifying whether fibers, chromosomes, spindles, starch granules, cell walls, cytoplasm and tissues contain crystals. In plant pathology, the invasion of bacteria often causes changes in the chemical properties of tissues, which can be identified by polarizing microscopy.
use
Polarizing microscope is an important instrument to study the optical properties of crystals, and it is also the basis of other crystal optical research methods (oil immersion method, Freudian method, etc.).
Polarizing microscope is an essential instrument to study and identify substances with birefringence by using the polarization characteristics of light, which can be used for single polarization observation, orthogonal polarization observation and cone light observation. A method of changing ordinary light into polarized light for microscopic examination to identify whether a substance is single refraction (isotropic peer) or birefringence (anisotropic).
Birefringence is the basic characteristic of crystals. Therefore, polarizing microscope is widely used in minerals, chemistry 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 of polarizing microscope.
