M Plan Apo HR 10X Objective Lens (Brightfield, Extra-High Resolving Power)
The M Plan Apo HR 10X is a high-performance 10x microscope objective designed for brightfield observation across the visible spectrum. As part of the HR (High Resolution) range, it is engineered to deliver extra-high resolving power, making it ideal for inspection and measurement applications where maximum clarity is required at mid-range magnification.
This objective features an infinity-corrected optical design and is corrected across 436–656 nm for consistent image quality and reliable colour reproduction. With a numerical aperture of 0.42, it provides excellent detail and contrast, achieving a resolving power of 0.7 µm. A working distance of 15 mm offers practical clearance while maintaining strong optical performance.
Compatible with VMU / FS-70 / MF-U / Hyper MF-U microscope systems, the M Plan Apo HR 10X is a premium option for precision brightfield microscopy where enhanced resolution is required.
