With an extraordinary 11mm working distance—more than 50 times longer than typical 50x objectives—this lens excels in applications requiring clearance for thick specimens, measurement probes, micromanipulation tools, or inspection of components with complex surface topography.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"font-family: 'Segoe UI Emoji', sans-serif;\"\u003eThe integrated EPI D (episcopic darkfield) capability enables high-contrast visualization of surface defects, scratches, contamination, and fine structural details that remain invisible under conventional brightfield illumination. This dual-mode functionality makes the objective invaluable for quality control inspection, failure analysis, and materials characterization where both general observation and defect detection are required. The 0.60 numerical aperture delivers excellent resolution while maintaining the extended working distance.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"font-family: 'Segoe UI Emoji', sans-serif;\"\u003eEngineered for Nikon's TU Plan series, this infinity-corrected objective features the robust 32mm thread standard used in industrial microscopy systems. The plan-corrected optical design ensures edge-to-edge sharpness across the entire field of view, critical for accurate measurement and documentation. This objective has seen only light use and features flawless optics, delivering performance indistinguishable from new at less than half the original cost.
