10X EO HR Infinity Corrected Objective

Product Details High Resolving Power Designed for use in Zoom Lens Systems Features Mitutoyo Standard M26 x 36 TPI Threads EO High Resolution Infinity Corrected Objectives are designed for high resolution over a small field of view. These objectives feature Mitutoyo standard M26 x 36 TPI threads and a 95mm parfocal length which allows them to be used interchangeably with Mitutoyo microscopes and accessories. While usable with Mitutoyo microscopes and accessories, these objectives perform best when used in a zoom lens system. EO High Resolution Infinity Corrected Objectives feature near-diffraction limited on axis performance. For longer working distance objectives that can be used in Mitutoyo systems, see our EO Infinity Corrected Long Working Distance Objectives .
