Nikon S Fluor 4X Microscope Objective

The Nikon CFI Super Fluor 4X is a premium low-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 and live cell observation. With a generous 15.5mm working distance, the Super Fluor 4X provides ample clearance for thick specimens, culture vessels, and micromanipulation tasks, making it ideal for screening applications, tissue section overview, and initial specimen survey before switching to higher magnifications. The wide field of view at 4X magnification enables efficient navigation and contextual imaging, while the high-quality fluorite optics ensure that image quality is never compromised. This objective is in excellent condition with flawless optics, offering professional-grade performance for laboratories using Nikon Eclipse, Ti, and Ni series microscopes.
