The MF measuring microscopes can be combined with Mitutoyo's vision unit to boost its performance and data management on a PC, further improving measuring efficiency and productivity.

Free Installation & Calibration on all Mitutoyo MF and MF-U Models.


  • Motorized model of the MF-UJ Series. Z-axis is motorized, and the stage can be operated using a remote box.
  • Using the optional vision unit enables the image AF function.
  • Illumination unit (reflected/transmitted) can be selected from a high-intensity LED or halogen bulb (required).
  • Variable aperture diaphragm (reflected/ transmitted) allows observation measurement while suppressing light diffraction.
  • A wide variety of optional accessories are offered.
  • Proven high-NA objectives from the FS optical system (long working distance type).
  • Integration of metallurgical and measurement microscope functions provide high-resolution observation and a high-accuracy measurement solution.
  • High-magnification observation up to 4000X.
  • MF-UE/UF is capable of performing Laser AF. The standard Laser AF function is equipped with the tracking function which maintains focus while the stage is in motion.
  • 1 Year warranty
