Olympus UPlanXAPO 4X Objective | 0.16 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 4× Extended Apochromat Objective is a high-quality microscope objective designed for broad overview imaging and preparatory scanning in laboratory workflows. With 4× magnification and a numerical aperture (NA) of 0.16, this objective delivers a wide field of view — ideal for scanning large areas of a specimen before switching to higher magnifications for detailed analysis.

Featuring extended apochromat optical correction, this objective reduces chromatic and spherical aberrations more effectively than standard plan achromats, producing sharp, flat images across the entire field. This optical performance is especially beneficial when imaging with broadband illumination or capturing overview mosaics where uniform clarity is essential.

The UPLanxApo 4× objective supports a long working distance, allowing for easier slide manipulation, larger specimens, and auxiliary tools use during preliminary imaging. Designed for versatile applications, it performs reliably in brightfield, fluorescence, and multi-modal microscopy settings that require a balance of field coverage and optical accuracy.

Whether deployed for initial specimen assessment, histological overview imaging, or general microscopy use, the 4× extended apochromat objective offers consistent performance that supports both research and clinical workflows.
