[0002] A metallographic microscope is a high-precision optical instrument that is primarily used to observe and study the metallographic structure of a sample. On-site metallographic testing has become a common method for evaluating mechanical properties. When testing components with complex shapes and limited spatial positions, a portable metallographic microscope needs to be placed in the area to be tested and manually controlled to find the field of view.
