M50 Brightfield / Darkfield Metallurgical Microscope
The Fein Optic M50 metallurgical microscope is a brightfield and darkfield microscope that provides high magnification for inspection of failures on metal parts or for viewing small particles. High quality Semi Apochromat BD metallurgical infinity corrected objectives provide clarity and resolution for viewing micron sized particles. The 12v, 100w halogen light provides even and bright illumination, especially if images need to be captured. The microscope provides polarization as well as DIC. Available with reflected light only or reflected and transmitted light.
