Features
The PLM-1/PLM-2 polarizing microscope is an essential instrument for the research and identification of birefringent substances by using the polarization characteristics of light. It is widely used in research and testing in the fields of geology, chemical industry, medical treatment, medicine, etc. It can also observe the crystal phase of liquid polymer materials, biopolymers and liquid crystal materials. It is an ideal instrument for research and teaching in scientific research institutions and colleges and universities. .
