Mi50 Inverted Metallurgical Brightfield/Darkfield DIC Microscope
The Fein Optic Mi50 inverted metallurgical microscope provides brightfield, darkfield, polarization and DIC. The large triple-layer mechanical stage has a working surface for placing large metal parts that need examination at high magnification. ECO friendly controls provide the ability to extend bulb life and save energy. LM Plan Achromat Brightfield / Darkfield metallurgical infinity corrected objectives provide a high numerical aperture for optical clarity and resolution.
