Polarizing Microscope

Polarizing microscope is a kind of microscope used to study so-called transparent and opaque anisotropic materials. It has important applications in geology, science and engineering. All materials with birefringence can be distinguished clearly under polarizing microscope. Of course, these materials can also be observed by dyeing method, but some of them are not available. Polarizing microscope must be used instead. Reflective polarizing microscope is a necessary instrument for the research and identification of birefringent substances by using the polarization characteristics of light. It can be used for single polarization observation, orthogonal polarization observation and cone light observation for users. Therefore, polarizing microscopy is widely used in minerals, polymers, fibers, glass, semiconductors, chemistry and other fields. In biology, many structures also have birefringence, which requires polarizing microscopy to distinguish them. In botany, such as identification of fibers, chromosomes, spindles, starch grains, cell walls and whether crystals exist in cytoplasm and tissues. In plant pathology, invasive pathogens often cause changes in the chemical properties of tissues, which can be identified by polarizing microscopy.
