🔧 Product Description

The Nikon CFI Super Plan Fluor High NA LWD 20X represents an exceptional combination of high numerical aperture, long working distance, and premium fluorite optics—features rarely found together in a single objective. This specialized objective is engineered for applications requiring both high resolution and extended working distance, such as imaging through thick culture vessels, microplates, or non-standard specimen preparations. The high numerical aperture of 0.7 provides superior resolution and light-gathering capability compared to standard long working distance objectives, while the extended working distance range of 1.3mm to 2.3mm (adjustable via correction collar) offers exceptional clearance for thick specimens, plastic culture vessels, and micromanipulation equipment. The integrated correction collar allows precise compensation for coverglass thickness variations and optical path differences introduced by culture vessels or mounting media, maintaining optimal image quality across diverse specimen types. Featuring advanced plan fluorite optics, this objective delivers exceptional flatness of field and superior chromatic correction across a broad wavelength range, making it ideal for multi-channel fluorescence microscopy, live cell imaging, and quantitative imaging applications. Compatible with Nikon's CFI60 infinity optical system, this objective integrates seamlessly with Eclipse, Ti2, and Ni-E series research microscopes, providing professional-grade performance for laboratories conducting advanced biological research where both resolution and working distance are critical.
