BMI800 Inverted Metallurgical Microscope is a high level research metallurgical microscope. It can identify and analyze not only a variety of metals, alloys, non-metallic material and the organizational structure and integrated circuits, but also micro-particles, wires, fibers, surface coating and so on. Digital cameras can be added to the trinocular tube to take images and make image analysis. DIC observation is optional.


BMI800 inverted metallurgical microscope is the best choice for material microscopy expert who requires high-performance optical tool. It supplies the best optical performance for material research, quality control, invalidation analysis and other challenging applications. It can be used in institutes, universities, reseearch centrers and laboratories to observe and identify the structure of various metal and alloy, it also can be used in electronics, chemical and instrumentation industry to observe the opaque materials and transparent materials, such as metal, ceramics, integrated circuits, electronic chips, printed circuit boards, LCD panels, film, powder, toner, wire, fibers, plated coatings, and other non-metallic materials and so on.


  • Infinite optical system provides excellent optical functions.
  • DIC observation is optional.
  • Meet most of your requirements by high performance optical system, technological innovation and high stability.
