In the process of observing metal materials and metallographic structure, Metallographic Microscope often encounters three common problems: glare on the surface of the sample, dark field of view, and imaging color distortion, which not only affect the observation effect, but also easily lead to misjudgment of metallographic structure. The following compiles practical fault causes and original solutions based on practical experience.
