EO Infinity-Corrected Long Working Distance Objectives

  • High Quality Optics in a Plan Apochromat Design
  • Long Working Distance Options
  • Sub-Micron Resolving Power

These objectives are made to the highest quality and standards, utilizing a strain-free optical system. They maintain a long working distance and offer high numerical apertures. With resolving power from 5 to 0.34 microns, these objectives work for a wide array of applications. All stated magnifications are based on a tube lens focal length of 200mm. Mounting thread is 26mm x 0.706mm pitch (36 TPI). Works with all Mitutoyo parts and can be placed directly in a system currently utilizing Mitutoyo objectives.
