Olympus UPlanXAPO 20X Objective | 0.80 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 20X Extended Apochromat Objective is a high-performance microscope objective designed for researchers and imaging professionals seeking reliable resolution, enhanced contrast, and consistent color fidelity. With 20× magnification and a numerical aperture (NA) of 0.80, this objective provides an optimal balance of resolving power and working distance — making it ideal for larger specimens or thicker samples that require more space between the lens and the subject.

Featuring extended apochromat correction, this objective reduces both chromatic and spherical aberrations across the visible spectrum, ensuring images remain sharp and flat from edge to edge. This makes it well-suited for a wide range of microscopy applications, including brightfield, fluorescence, and advanced multi-modal imaging.

One of the key advantages of the UPLanxApo 20x is its long working distance (~5.5 mm), which allows for easier sample manipulation, illumination, and the use of auxiliary devices such as microinjection or patch-clamp tools without compromising optical performance.

Whether used in biological research, histology, or materials science studies, this objective delivers dependable optical performance for laboratories that demand both flexibility and clarity.
