Description
XJL-302 upright metallurgical microscope is suitable to observe surfaces of opaque objects. It is equipped excellent UIS optical system and modularization function design so that update system expediently and achieved polarization, darkfield observation. The compact and steady main frame body is an embodiment of the shock resistance. The ideal ergonomic design is adopted in this unit and has an easier operation and wider space. This is an ideal optical instrument for micro observation in metallographic structure and surface morphology. It is suitable for research in metallography, mineralogy, precision engineering, etc.
