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.\n\u003c\/p\u003e\n\u003chr\u003e\n\u003cp class=\"MsoNormal\" style=\"font-family: 'Segoe UI Emoji', sans-serif;\"\u003e\u003cstrong\u003e🔎 Typical Applications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul style=\"font-family: 'Segoe UI Emoji', sans-serif;\"\u003e\n\u003cli\u003eFluorescence microscopy and multi-channel imaging\u003c\/li\u003e\n\u003cli\u003eImmunofluorescence and antibody staining studies\u003c\/li\u003e\n\u003cli\u003eLive cell imaging and tissue culture observation\u003c\/li\u003e\n\u003cli\u003eHistopathology and tissue section examination\u003c\/li\u003e\n\u003cli\u003eCellular and subcellular imaging\u003c\/li\u003e\n\u003cli\u003eBrightfield and phase contrast microscopy\u003c\/li\u003e\n\u003cli\u003eClinical diagnostics and pathology\u003c\/li\u003e\n\u003cli\u003eQuality control and materials inspection\u003c\/li\u003e\n\u003cli\u003eEducational and research microscopy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003cp class=\"MsoNormal\" style=\"font-family: 'Segoe UI Emoji', sans-serif;\"\u003e\u003cstrong\u003e📊 Key Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable border=\"1\" cellpadding=\"8\" cellspacing=\"0\" style=\"font-family: 'Segoe UI Emoji', sans-serif; border-collapse: collapse; width: 100%;\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 40%;\"\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 60%;\"\u003e\u003cstrong\u003eDetails\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel \/ Catalog Number\u003c\/td\u003e\n\u003ctd\u003eCFI Plan Fluor 20X \/ MRH00201\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMagnification\u003c\/td\u003e\n\u003ctd\u003e20X\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumerical Aperture (NA)\u003c\/td\u003e\n\u003ctd\u003e0.50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptical Design\u003c\/td\u003e\n\u003ctd\u003ePlan Fluorite (Semi-Apochromat), Infinity-Corrected (CFI60)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eImmersion Type\u003c\/td\u003e\n\u003ctd\u003eDry (air)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWorking Distance\u003c\/td\u003e\n\u003ctd\u003e2.1mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThread Type\u003c\/td\u003e\n\u003ctd\u003eM25 (25mm metric thread)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatibility\u003c\/td\u003e\n\u003ctd\u003eAll Nikon CFI60 infinity-corrected microscopes (Eclipse, Ti, Ni series)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptical Correction\u003c\/td\u003e\n\u003ctd\u003ePlan (flat field), Fluorite (enhanced chromatic correction)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Applications\u003c\/td\u003e\n\u003ctd\u003eFluorescence, brightfield, phase contrast, immunofluorescence\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCondition\u003c\/td\u003e\n\u003ctd\u003eExcellent, flawless optics\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd\u003eJapan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003chr\u003e\n\u003cp class=\"MsoNormal\" style=\"font-family: 'Segoe UI Emoji', sans-serif;\"\u003e\u003cem\u003eUniversity purchase orders are welcome and accepted.
