M Plan Apo HR 50X Objective Lens (Brightfield, Extra-High Resolving Power)
The M Plan Apo HR 50X is a premium 50x metallurgical microscope objective designed for brightfield observation across the visible spectrum. As part of the HR (High Resolution) series, this objective is engineered for maximum detail and contrast, making it ideal for demanding inspection and measurement applications.
With a high numerical aperture of 0.75, it delivers exceptional fine-detail imaging with a resolving power of 0.4 µm. The objective is infinity corrected and optically optimised across 436–656 nm, ensuring consistent performance and reliable image quality. A working distance of 5.2 mm provides practical clearance while maintaining extremely high optical resolution.
Compatible with VMU / FS-70 / MF-U / Hyper MF-U microscope systems, the M Plan Apo HR 50X is an excellent choice for precision surface inspection where enhanced resolving power is essential.
