The 378 series objectives from Mitutoyo are optical systems that carry out the longest working distance and infinity correction in the market. Chromatic aberrations associated with imaging are independently rectified by these objectives, which give a flat image that can be viewed with any kind of microscope. Flexible and easy observation of images at higher magnifications has been made possible through these ground-breaking objectives.
Difficult-to-observe work pieces with awkward projections can be observed clearly due to the brilliant clearance offered by the long working distance objectives between the surface of the lens and the work piece. The 378 series also offers special objectives with correction for near IR, and near and far UV radiations.
