The YP-90 transmission reflection polarizing microscope is an essential instrument for studying and identifying substances with birefringence using the polarization characteristics of light. It can be used by a wide range of users for single polarization observation, orthogonal polarization observation, and cone light observation. Widely used in research and testing in the fields of geology, chemical engineering, production, and research and development, it can also be used for crystal phase observation of liquid polymer materials, biopolymers, and liquid crystal materials. It is an ideal instrument for research institutions and universities to conduct research and teaching.
