Mitutoyo Infinity Corrected Long Working Distance Objectives
• Long Working Distances, Bright Field Inspection
• High Quality Plan Apochromat Design
• Flat Image Surface over Entire Field of View
Mitutoyo’s objectives are world-renowned for setting the standard of excellence for long working distance
microscope optics. They have achieved the best combination of working distance and optical performance by
using a new approach and avoiding outdated conventions used by competitors. In order to maintain as high an
NA and contrast as possible, the lenses are all Plan Apochromats. An apochromatic objective lens is chromatic
aberration corrected for red, blue, and yellow. Optimized for bright field illumination (incident illumination
parallel to optical axis), these lenses are ideal for in-line illumination applications. For an infinity correction
system, a tube lens is required. M Plan APO HR series objectives offer increased resolving power. All stated
magnifications are based on a tube lens focal length of 200 mm.
Compatible with MT-1, MT-2, and MT-4 Tube Lenses. For complete specifications, see page 293
