The HN-302/302BD upright metallographic microscope is suitable for microscopic observation of opaque objects. By adopting an excellent infinite distance optical system and modular functional design concept, it is convenient to upgrade the system and achieve functions such as polarization observation and dark field observation. The compact and stable high rigidity body fully reflects the anti vibration requirements of microscopic operations. An ideal design that meets the requirements of ergonomics, making operation more convenient and comfortable, and providing a wider space. Suitable for microscopic observation of metallographic structure and surface morphology, it is an ideal instrument for research in metallurgy, mineralogy, and precision engineering
