Olympus UPlanFL N 4X Objective | 0.13 NA Dry, Infinity Corrected

The Olympus UPLFLN 4× Objective is a reliable microscope objective engineered for overview and low-power imaging in research, clinical, and educational settings. With 4× magnification and a numerical aperture (NA) of 0.13, this objective offers a broad field of view perfect for initial slide surveys, specimen mapping, and large sample observation.

Featuring a Plan Fluor optical design, this lens delivers excellent edge-to-edge sharpness by minimizing chromatic and spherical aberrations. The result is crisp, flat imaging across the entire field — especially important for overview imaging where uniform clarity helps guide subsequent high-magnification examinations.

With an extended working distance of approximately 18.5 mm, the UPLFLN 4× objective provides substantial space between the specimen and the lens, making it easier to manipulate samples or use auxiliary tools without risk of contact. This, coupled with its standard RMS threaded mount, ensures broad compatibility with common upright microscopy systems.
