VM4000 Series upriht metallurgical microscopes are suitable to observe surface of opaque object or transparent object. They are equipped with excellent UIS optical system and modularization function design so that provited excellent optical quilatity and operation performance, update system expediently and provided observation in reflected or transmitted and mixed illumination, 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, mineralogy, precision engineering, electronics, ect.

Double layer mechanical stage, size of 210mm x 140mm, move range: 63mm x 50mm. The design is in reason so that the operator feel easy and comfort.

Collector for halogen lamp illumination and integrated field diaphragm it can provide clear and bright image. Abbe condenser NA.1.25 rack & pinion adjustable.

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

By adding the appurtenance such 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.
