1、 The purpose of the instrument：

The YPN-200 series polarizing microscope is an instrument that uses the polarization characteristics of light to study and identify substances with birefringence. It has a wide range of applications in medicine, such as observing the structural details of crystalline inclusions, nerve fibers, animal muscles, plant fibers, etc. in teeth, bones, hair, and living cells, and analyzing the process of degeneration. It is also possible to observe the crystal structure of various salts in inorganic chemistry, which is not visible under natural light. Equipped with high-precision heating tables, mainly used in teaching and laboratories
