M Plan Apo HR 5X Objective Lens (Brightfield, Extra-High Resolving Power)
The M Plan Apo HR 5X is a high-performance 5x microscope objective designed for brightfield observation across the visible spectrum. As part of the HR (High Resolution) range, this objective is engineered to deliver extra-high resolving power, making it ideal for inspection tasks where maximum detail is required at lower magnifications.
With a working distance of 25.5 mm, it provides excellent clearance while maintaining strong optical performance. The objective features an infinity-corrected design and is corrected across 436–656 nm for consistent imaging and reliable colour reproduction. With a numerical aperture of 0.21, it achieves a resolving power of 1.3 µm while maintaining a practical depth of field of 6.2 µm.
Compatible with VMU / FS-70 / MF-U / Hyper MF-U microscope systems, the M Plan Apo HR 5X is an excellent choice for high-clarity, wide-area observation where enhanced resolution is required.
