M Plan Apo SL 100X Objective Lens (Brightfield, Extra-Long Working Distance)
The M Plan Apo SL 100X is a precision 100x metallurgical microscope objective designed for brightfield observation across the visible spectrum. With an extra-long working distance of 13 mm, it is ideal for high-magnification inspection where additional clearance is required between the lens and the sample.
This objective is infinity corrected and optimised across a wide wavelength range (436–656 nm) for consistent optical performance. Featuring a numerical aperture of 0.55, it delivers excellent detail with a resolving power of 0.5 µm and a depth of field of 0.9 µm, making it well suited for demanding surface inspection and precision observation tasks.
Compatible with VMU / FS-70 / MF-U / Hyper MF-U microscope systems, the M Plan Apo SL 100X offers dependable high-magnification imaging in a robust design.
