Olympus UPlanXAPO 40X Oil Immersion Objective | 1.40 NA Extended Apochromat, Infinity Corrected

Why Choose UPLXAPO Over Standard Objectives?

Standard objectives (Plan Achromat or Plan Fluorite) provide good performance for routine imaging but fall short in advanced applications.

UPLXAPO objectives offer:

・Significantly higher numerical aperture for better resolution
・Superior chromatic correction for fluorescence and multi-channel imaging
・Flat field across large sensors — ideal for digital imaging
・Improved signal collection for low-light applications

This makes UPLXAPO the preferred choice for confocal, fluorescence, and high-resolution research imaging

The Olympus UPLanxApo 40×Oil Extended Apochromat Objective is a precision-engineered microscope objective designed for researchers, clinicians, and imaging professionals who require high resolution, contrast, and flat imaging across the field of view. With a numerical aperture of 1.40, this 40× oil-immersion lens offers excellent light-gathering capability and superb detail resolution in demanding microscopy applications.

Featuring plan apochromat correction, this objective minimizes chromatic and spherical aberrations, ensuring sharp, distortion-free images from edge to edge. Its oil immersion design further increases numerical aperture and enhances image brightness — especially important when resolving fine structures or imaging fluorescent samples.

Whether you're imaging fixed specimens in brightfield or capturing fluorescence signals with high fidelity, the UPLanxApo 40× delivers the optical performance and consistency that advanced microscopy workflows demand.
