The Plan Fluor optical design delivers bright, flat, and well-corrected images across the full field of view, while the PH2 phase ring enables crisp contrast on unstained, living specimens.\u003c\/p\u003e\u003chr\u003e\u003ch2\u003e🔎 Typical Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLive-cell phase contrast imaging\u003c\/li\u003e\n\u003cli\u003eCell culture monitoring in multi-well plates and flasks\u003c\/li\u003e\n\u003cli\u003eInverted microscopy on Nikon Ti, TE, and TS platforms\u003c\/li\u003e\n\u003cli\u003eBrightfield and phase contrast workflows in biology and life sciences labs\u003c\/li\u003e\n\u003cli\u003eUniversity and research laboratory use\u003c\/li\u003e\n\u003c\/ul\u003e\u003chr\u003e\u003ch2\u003e📊 Key Specifications\u003c\/h2\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eDetails\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMagnification\u003c\/td\u003e\n\u003ctd\u003e40X\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptical Correction\u003c\/td\u003e\n\u003ctd\u003ePlan Fluor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumerical Aperture (NA)\u003c\/td\u003e\n\u003ctd\u003e0.60\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWorking Distance\u003c\/td\u003e\n\u003ctd\u003e3.7–2.7 mm (ELWD)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhase Ring\u003c\/td\u003e\n\u003ctd\u003ePH2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThread\u003c\/td\u003e\n\u003ctd\u003eM25\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatibility\u003c\/td\u003e\n\u003ctd\u003eNikon Ti, TE \u0026amp; TS Inverted Microscopes\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\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003eMRH38420\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\u003c\/tbody\u003e\u003c\/table\u003e\u003chr\u003e\u003cp\u003e\u003cem\u003eUniversity purchase orders are accepted.
