EO High Resolution Infinity Corrected Objectives
• High Resolving Power
• Long Working Distance
• Compatible with Mitutoyo Microscopes and Accessories
The EO Infinity corrected objectives offer increased resolution when compared to Mitutoyo’s M Plan Apo
series while maintaining long working distances and near-diffraction limited performance. Featuring the Mitutoyo
standard M26 x 0,706 thread and 95 mm parfocal length, these objectives can be used interchangeably

EO Infinity-Corrected Long Working Distance Objectives
• High Quality Optics in a Plan Apochromat Design
• Long and Ultra 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 200 mm. Mounting thread is 26 mm x 0,706 mm pitch (36 TPI). Works with all Mitutoyo
parts and can be placed directly in a system currently utilizing Mitutoyo objectives. All dimensions are in mm.
