• High Resolving Power
• Long Working Distance
• Compatible with Mitutoyo Microscopes and Accessories
The EO In nity corrected objectives o er increased resolution when compared to Mitutoyo’s M Plan Apo
series while maintaining long working distances and near-di raction limited performance. Featuring the Mitutoyo
standard M26 x 0.706 thread and 95mm parfocal length, these objectives can be used interchangeably

Objectives
Compact Objective Assemblies
• Lightweight Design with Compact Form Factor
• Con gurable Magni cation Using Spacers
• Optimized For Long Working Distances
TECHSPEC® Compact Objective Assemblies are designed to reduce the overall weight and size of an imaging system
while maintaining optical performance. While traditional objective systems typically require long tube lengths
and tube lenses, TECHSPEC® Compact Objective Assemblies optimize each objective to allow for shorter tube
lengths. Standardized 30mm outer diameters and C-mount threading ease integration into system assemblies.
Magni cation can be easily increased by adding spacers to increase the tube length. Each lens has a broadband
anti-re ection coating to provide even and maximized light transmission in the visible spectrum.
