Mitutoyo BD Plan Apo SL 50x Objective for MF-U Measuring Microscopes (Brightfield / Darkfield)
MitutoyoThe Mitutoyo 378 Series objectives have the world's longest working distance and an infinity correction optical system. These objectives provide flexible observation at high magnifications and independent correction of chromatic aberration.
- The long working distance objectives provide excellent clearance between the lens surface and the workpiece surface in focus, making it possible to observe workpieces which are usually hard-to-focus because of awkward projections.
- The metallurgical plan apochromatic (M Plan Apo) objective provides a flat, chromatic aberration-free image throughout the field of view, making it suitable for any type of microscope.
- Specially designed objectives also are available with correction for near-infrared radiation, near-ultraviolet radiation, and ultraviolet radiation, or various thicknesses of LCD screen glasses.
- The mounting screw threads of objectives are designed to conform to JIS B-7141-1988.
- Super Long (SL) Working Distance
- For MF-UC & MF-UD Models
- Compatible observation method: Bright-field observation, dark-field observation, simple polarized observation, differential interference observation
- Advantage: Dark-field observation is also supported while maintaining the performance of the M Plan Apo objective series.
