Olympus UPlanFL N 40X Objective | 0.75 NA Plan Fluorite, Infinity Corrected

The Olympus UPLFLN 40× Objective is a high-performance microscope lens engineered for research and clinical imaging applications that demand excellent resolution, uniform contrast, and optical fidelity. With 40× magnification and a numerical aperture (NA) of 0.75, this objective delivers crisp, high-contrast images across a broad range of microscopy modalities — from brightfield and phase contrast to epifluorescence and high-resolution documentation.

At the heart of the UPLFLN 40× is its Plan Fluor optical design, which significantly reduces chromatic and spherical aberrations while maintaining a flat field of focus. This ensures that image sharpness and contrast remain consistent from the center of the field to the edges — a key feature for quantitative analysis, stitching, and detailed inspection.

The lens offers a broad spectral transmission range, providing dependable performance throughout the visible spectrum and into the near-infrared. This makes it particularly suited for advanced imaging techniques where signal capture across wavelengths is critical, such as multi-channel fluorescence.

Compatible with microscopes featuring standard RMS threading, the UPLFLN 40× objective integrates seamlessly with most upright research microscope stands, making it a versatile choice for laboratories, clinical facilities, and educational institutions that demand a balance of power, clarity, and reliability.
