The M Plan Apo objective offers an extra-high resolving power with flat, chromatic aberration-free image throughout the field of view, making it suitable for a wide range of applications.
Features & Benefits
The Mitutoyo 378 Series Objectives have the world’s longest working distance and an infinity correction optical system. These objectives provide flexible observation at ultra-high magnifications and independent correction of chromatic aberration. The higher numerical aperture values indicate greater optical resolution.
- Long working distance provides clearance between the lens surface and the workpiece surface in focus for large or awkward workpieces
- The mounting screw threads of objectives are M26 x 36TPI and conform to JIS B-7141-1988
- M Plan Apo high-resolution bright field objectives have magnification powers of: 5x, 10x, 50x and 100x
