Features:
XJL-20/20BD Inverted metallurgical microscope 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.
- Adopt infinity optical system and modularization function design.
- Long W.D bright or dark field plan objectives (no cover glass), the field of view is widely and clear.
- Wide-field plan eyepieces: field number Ô22mm.
- Coaxial coarse/fine focus system, with tensional adjustable and up stop, minimum division of fine focusing: 2μm.
- Integrated polarization observation device, the polarizer can be circumrotated for 360°.
- The Epi- illumination is 12V 50W halogen lamp and the lamp box cover can be revolved, replacing lamp facility and safety. The transmitted illumination is 12V 30W halogen lamp and adding radiator.
- Trinocular can be observation for eyepieces and microphotography in 100% light flux, suits for dark field microphotography.
