🧪 Product Description (Long-Form)

The Olympus UPLXAPO 40X Extended Apochromat Objective is a high-performance microscope objective engineered for researchers and imaging professionals who demand high resolution, color fidelity, and imaging precision across a wide range of applications. With 40× magnification and a high numerical aperture (NA) of 0.95, this air-immersion objective delivers excellent detail and contrast, making it ideal for examinations where subtle specimen features matter.

Featuring Extended Apochromat optical correction, this objective reduces chromatic and spherical aberrations more effectively than standard plan achromats, producing sharp, flat images from center to edge. Such correction is especially important when imaging with broadband illumination or when stitching multiple images for large field views.

The adjustable correction collar allows users to compensate for variations in cover glass thickness (approximately 0.11–0.23 mm), optimizing clarity and performance across laboratory workflows. With a working distance of ~0.18 mm, this objective balances close specimen access with optical performance for demanding imaging tasks.

Optimized for use in brightfield, fluorescence, and advanced microscopy systems, the UPLXAPO 40× is also effective across a broad wavelength range — from ultraviolet to near-infrared — enabling versatile imaging from visible-spectrum work to near-IR applications.
