Up-right Bright/Dark Field Metallurgical Microscope

L3230BD

 

 

L3203/L3220/L3230/L3230BD 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.

Advantage

1) Adopt infinity optical system and modularization function design.
2) Long W.D bright or dark field plan objectives (no cover glass), the field of view is widely and clear.
3) Wide-field plan eyepieces: field number Φ22mm.
4) Coaxial coarse/fine focus system, with tensional adjustable and up stop, minimum division of fine focusing: 2μmm.
5) Integrated polarization observation device, the polarizer can be circumrotated for 360˚.
6) The Epi- illumination is 12V 50W halogen lamp and the lamp box cover can be revolved, replacing lamp facility and safety.
7) The transmitted illumination is 12V 30W halogen lamp and adding radiator.
8) Trinocular can be observation for eyepieces and microphotography in 100% light flux, suits for dark field microphotography.
