Application Fields of Polarizing Microscopes
Polarization microscope is an essential instrument for studying and identifying substances with birefringence using the polarization characteristics of light. It can be used for single polarization observation, orthogonal polarization observation, and cone light observation. The method of changing ordinary light into polarized light for mirror inspection to distinguish whether a substance is single refractive (isotropic) or birefringent (anisotropic). Birefringence is a fundamental characteristic of crystals. Therefore, polarizing microscopes are widely used in fields such as minerals and chemistry. In biology, many structures also have birefringence, which requires the use of polarizing microscopes to distinguish them. In botany, such as identifying fibers, chromosomes, spindles, starch granules, cell walls, and whether there are 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 polarized light microscopy. Polarized microscopy is commonly used in human and animal studies to identify bones, teeth, cholesterol, nerve fibers, tumor cells, striated muscles, and hair. Today we will introduce the application fields of polarizing microscopes.
1. In the field of biology, different fibrous protein structures exhibit significant anisotropy, and the detailed arrangement of molecules in these fibers can be obtained using a polarizing microscope. Such as collagen, spindle fibers during cell division, etc.
2. Identification of various biological and non biological materials, such as starch property identification, drug ingredient identification, fiber, liquid crystal, DNA crystal, etc.
3. Geological and mineral analysis: such as the analysis of minerals and crystals.
4. Medical analysis: such as stone formation, uric acid crystal testing, arthritis, etc.
