With a 0.45 numerical aperture and Plan Fluor optical correction, this objective offers high-contrast, flat-field imaging across the field of view. Its extended working distance makes it ideal for imaging through thicker cover glasses, plastic-bottom dishes, or larger media volumes. DIC compatibility allows enhanced contrast for transparent samples without staining.\u003c\/p\u003e\n\n\u003ch3\u003eCondition\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eRefurbished\/Used\u003c\/strong\u003e\u003cbr\u003e\n(This product has been inspected and verified to meet manufacturer specifications)\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e20x magnification with 0.45 NA for crisp, detailed imaging\u003c\/li\u003e\n  \u003cli\u003eExtra Long Working Distance (ELWD) for improved specimen accessibility\u003c\/li\u003e\n  \u003cli\u003ePlan Fluor optics ensure flat-field, high-contrast performance\u003c\/li\u003e\n  \u003cli\u003eDIC-compatible for enhanced contrast in transparent specimens\u003c\/li\u003e\n  \u003cli\u003eOptimized for both fluorescence and brightfield imaging\u003c\/li\u003e\n  \u003cli\u003eM25 thread for compatibility with Nikon upright research microscopes\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eLive-cell fluorescence imaging\u003c\/li\u003e\n  \u003cli\u003eDifferential Interference Contrast (DIC) microscopy\u003c\/li\u003e\n  \u003cli\u003eThick sample or plastic dish observation\u003c\/li\u003e\n  \u003cli\u003eRoutine and research biological imaging\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctr\u003e\n    \u003cth\u003eSpecification\u003c\/th\u003e\n    \u003cth\u003eDetails\u003c\/th\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003eManufacturer\u003c\/td\u003e\n    \u003ctd\u003eNikon\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003eModel\u003c\/td\u003e\n    \u003ctd\u003ePlan Fluor ELWD 20x\/0.45 DIC L\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\u003c\/td\u003e\n    \u003ctd\u003e0.45\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003eOptical Correction\u003c\/td\u003e\n    \u003ctd\u003ePlan Fluor (flat-field)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003eContrast Techniques\u003c\/td\u003e\n    \u003ctd\u003eDIC, Brightfield, Fluorescence\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003eWorking Distance\u003c\/td\u003e\n    \u003ctd\u003eExtra Long Working Distance (ELWD)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003eThread Size\u003c\/td\u003e\n    \u003ctd\u003eM25\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003eOptical System\u003c\/td\u003e\n    \u003ctd\u003eInfinity-corrected\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003eIntended Use\u003c\/td\u003e\n    \u003ctd\u003eUpright compound microscopes\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n","brand":"Coastal Microscopes","offers":[{"title":"Default Title","offer_id":47244012749054,"sku":"51598","price":1000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0693\/7860\/5310\/files\/Nikon_obj_20x_51598_1.png?v=1774687891","url":"https:\/\/coastalmicroscopes.com\/products\/nikon-plan-fluor-elwd-dic-l-n1-20x-0-45-m25-thread-size-microscope-objective-51598","provider":"Coastal Microscopes","version":"1.0","type":"link"}
