Nikon CFI Plan Fluor 20X Microscope Objective

The Nikon CFI Plan Fluor 20X is a versatile high-magnification objective engineered with advanced fluorite optical elements to deliver superior chromatic correction and high transmission across a broad wavelength range. As part of Nikon's renowned CFI60 infinity optical system, this objective provides exceptional image quality for both brightfield and fluorescence microscopy applications. The fluorite glass elements significantly reduce chromatic aberration compared to standard achromat objectives, ensuring accurate color reproduction and improved contrast—particularly valuable in multi-channel fluorescence imaging, immunofluorescence studies, and live cell observation. With a numerical aperture of 0.50, the Plan Fluor 20X provides excellent resolution and light-gathering capability for detailed cellular imaging, while the 2.1mm working distance accommodates standard microscope slides and coverslips. The plan optical design ensures exceptional flatness of field across the entire image, delivering edge-to-edge sharpness critical for digital imaging, photomicrography, and quantitative analysis. This objective is in excellent condition with flawless optics, offering professional-grade performance for laboratories using Nikon Eclipse, Ti, and Ni series microscopes at an exceptional value.
