In what ways is the MF-U series of Mitutoyo microscope unique from others? The MF-U series of Mitutoyo measuring microscope stands out from the other designs with its clear observation image and its incredible detection of microscopic flaws and asperities. Top-notch color quality, ultra-long working distance, and an apochromatic design that eliminates any chromatic aberration makes the MF-U an excellent choice. Additionally, these microscopes go above and beyond the standard availability of bright-field observation to also include the options of differential interference observation, simple polarized observation, and dark-field observation. The available polarization unit that comes with the MF-U series Mitutoyo measuring microscope increases image contrast when using a low-magnification lens.
