Our inverted metallurgical microscope is a specialized optical instrument designed for the examination and analysis of opaque materials, particularly in metallurgy and materials science. Unlike traditional microscopes, it has its light source and objective lenses positioned above the specimen, making it ideal for viewing polished metal samples, ceramics, and other solid materials that cannot be made transparent. Inverted metallurgical microscopes often feature polarized light, darkfield illumination, and advanced imaging capabilities for inspecting the microstructure, composition, and defects in metallic alloys and materials.
