Polarizing microscope specialized in material microstructure observation, crystal structure analysis, and stress analysis in manufacturing. Used for crystal grain boundary observation of metallic materials, internal stress measurement of resin and plastic components, orientation confirmation of fiber-reinforced materials, and microstructure inspection of welded joints. Equipped with polarizing filters and analyzers to visualize optical properties of birefringent materials. Distinguished from metallurgical microscopes by polarization functionality for detailed analysis of anisotropic materials. Essential precision optical instrument for quality control and material development departments. Includes transmitted light and reflected light compatible models with digital image acquisition systems.
