The IXG-43 seri inverted metallographic microscope adopts an excellent infinite optical system and modular functional design concept, allowing for easy system upgrades and enabling functions such as polarized observation and dark-field observation. The compact and stable high-rigidity body fully meets the requirements for anti-vibration operation of microscopes. The ideal design that conforms to ergonomic requirements makes operation more convenient and comfortable, providing a wider working space. It is suitable for microscopic observation of metallographic structure and surface morphology, making it an ideal instrument for studies in metallurgy, mineralogy, and precision engineering.
