Description

The Mitutoyo 5× M-Plan Apo HR Objective Lens (378-787-16) provides higher resolution and contrast than the standard series at the same magnification. With a 0.21 NA and 27 mm long working distance, this HR variant delivers sharper images and improved colour fidelity across the visible spectrum.

Part of Mitutoyo’s world-renowned plan-apochromatic, infinity-corrected objective line, it produces a flat field with precise chromatic correction. This lens is widely used in materials analysis, electronics inspection, and precision measurement applications that demand enhanced detail.
