VM4800 & VM4800BD upright metallurgical microscope is suitable to observe surfaces of opaque object. It is equipped excellent UIS optical system and modularization function design so that update system expediently and achieved polarization, dark field observation. Compact and steady main frame body is embodiment for the shock resistance. The ideal ergonomic design is adopted in this unit and has easier operation and wider space. This is ideal optical instrument for micro observation in metallographic structure and surface morphology. It is suitable for research in metallography, mineralogy, precision engineering, etc.

The gemel mode trinocular is inclined 30°. The operator cervix and shoulder are released from tired in period of time keeping bow or head-up. The eyepiece field of view number is Φ22mm and eyepiece can be added. Adopted Epi-illumination system, integrated field diaphragm, aperture diaphragm and (Y,B,G, Ground glass) switching device. Push-pull analyzer and polarizer.

Equip high quality bright and dark field objectives and dark field illumination device. Avoid the stray light of illumination system and improve the image quality in the dark field.

By adding the appurtenance shch as CCD adapter digital camera adapter and single-reverse digital camera adapter and etc. It can achieve high clear observation mode of camera and vidicon.
