Mitutoyo Tube Lenses function as secondary lenses to form an image using any of the Mitutoyo Infinity Corrected Objectives, They are economical alternatives to the FS70 Microscope or Infinitube® In-line Assembly Unit. Several options are available, depending upon system requirements. The MT-4 and MT-40 are designed for end-user integration and can easily be used with any C-Mount camera with our Mitutoyo C-Mount Camera Extension Tube #56-992. Mitutoyo Tube Lenses MT-4 Tube Lens is recommended for use with Objectives from 1X to 20X magnification, while the MT-40 is recommended for use with Objectives with >20X magnification.

The MT-2 Tube Lens is similar to the MT-1 but with an effective focal length of 400mm, providing twice the stated magnification for any of the Mitutoyo objectives. The MT-L and MT-L4 lenses are designed for the M Plan NUV and M Plan UV series of objectives, respectively. NIR and zoom tube lenses are also available through our line of Precision Zoom Lenses.
