BMU700BD Upright Metallurgical Microscope with BF/DF/POL and Optional DIC Nomarski imaging


$3,999.00 $7,000.00

The BMU700BD is one the best upright industrial microscope for metallography. It is mainly used to study microstructure, macrostructure and microstructure of fracture of metals, plastics, polymers and minerals, imaging , qualitative and quantitative characterization of the microstructure contains material, sample preparation and inspection in materials science, research and the characterization labs. It is great tool to study the composition and characterization of materials and microstructure, grain, corrosion, metallic and non-metallic inclusions, crystal defects (such as dislocations), analysis such as the number, morphology, size, distribution, orientation, spatial arrangement etc..


  1. One of  the world’s best infinite dual color correction and contrast enhancement (ICCS) optical system, to provide users with the most sharp image.
  2. It has brightfield, darkfield and polarization imaging modes
  3. Optional DIC Nomarski and Fluorescence imaging for reflected light and transmitted polarization.

BMU700BD Upright Metallurgical Microscope

BMU700BD series upright metallurgical microscope is suitable to observe surface of opaque, semi-  or transparent objects. It is equipped with excellent UIS optical system and modularization function design. It provides excellent optical quality and operation performance, observation in reflected or transmitted and mixed illumination, brightfield, polarizing observation, dark field observation. These instruments have beautiful sculpt, convenient control and clear image. They are the ideal instrument in research work in biology, metallography, semiconductors, mineralogy, precision engineering, electronics, etc.
