Telecentric Optical System
In order not to change the observing magnification, even at low magnification (10X or less) where the objective’s precise working distance is difficult to accurately reproduce because of a wide focal depth, this series adopts the telecentric optical system that reduces the magnification error due to a slight variation in the working distance.
Also, the MF series objectives are manufactured with a more accurate magnification due to Mitutoyo’s unique specification that surpasses JIS Standards. This optimizes comparative measurement with a reticle.
