MTL.02.302APO Upright Metallurgical Trino with APO Objective
Description and Notes

MTL.02.302APOmetallurgical 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.
Features:
▲ M Plan APO Long Working Distance Objective and wide-field eyepieces, can get clear pictures and wide view field
▲ With large move range mechanical stages,moving range:8"X8"(204mmX204mm)
▲ Coaxial coarse/fine focus system, with tensional adjustable and up stop, minimum division of fine focusing: 0.8μm
▲ 12V 50 halogen lamp, adjustable brightness
▲ Trinocular, can switch to normally/polarize observation, brightfield/darkfield observation. can send
100% of light to the binocular eyepieces or to the top port
