Polarizing microscope is a microscope used to study so-called transparent and opaque anisotropic materials, and has important applications in science and engineering majors such as geology. "Substances with birefringence can be clearly distinguished under a polarizing microscope. Of course, these substances can also be observed using staining methods, but some are not available and must be observed using a polarizing microscope.". Reflective polarizing microscope is a necessary instrument for studying and identifying substances with birefringence using the polarization characteristics of light. It can be used by users for single polarized light observation, orthogonal polarized light observation, and cone light observation.
