M Plan Apo 100X Objective Lens (Brightfield, High N.A. for Fine Detail)
The M Plan Apo 100X is a high-performance 100x metallurgical microscope objective designed for brightfield observation across the visible spectrum. With a numerical aperture of 0.7, it delivers excellent fine-detail imaging and improved resolving power for demanding inspection and measurement applications.
This objective features an infinity-corrected optical design and is corrected across 436–656 nm, ensuring consistent image quality and reliable colour performance. With a 6 mm working distance, it provides a practical balance between high magnification and sample clearance.
Compatible with VMU / FS-70 / MF-U / Hyper MF-U microscope systems, the M Plan Apo 100X is a strong choice for precision surface inspection where maximum detail is required.
Note: To avoid optical flare when using coaxial illumination, 1x objectives should be used together with a polarisation unit and an attached 1/4 wavelength plate.
