Olympus UPLANSAPO 40x Objective

The Olympus UPLANSAPO 40x objective represents the pinnacle of optical engineering, combining super apochromat correction with an adjustable correction collar for ultimate imaging performance across the most demanding microscopy applications. The "UPLANSAPO" designation indicates Universal Plan Super Apochromat optics, delivering chromatic correction across four wavelengths and spherical aberration correction at multiple wavelengths, ensuring color-accurate, high-contrast images with minimal optical artifacts from UV through visible to near-infrared wavelengths. This level of correction is essential for critical multi-color fluorescence imaging, quantitative microscopy, and applications where faithful color reproduction across the entire spectrum is paramount. At 40x magnification with 0.95 numerical aperture, this objective delivers exceptional resolution approaching the theoretical limits of light microscopy, enabling visualization of the finest cellular structures and subcellular details. The integrated correction collar allows precise compensation for variations in coverslip thickness (0.11-0.23mm), mounting media refractive index, and temperature-induced aberrations, ensuring optimal optical performance across diverse specimen preparations. The 0.18mm working distance accommodates standard microscope slides with #1.5 coverslips. The RMS thread mount ensures compatibility with a wide range of microscope platforms. This objective is the ultimate tool for advanced fluorescence microscopy, confocal imaging, live-cell studies, and any application demanding the highest optical performance and versatility.
