The UCPLANFLN (Universal Plan Fluorite) optical design combines plan (flat-field) correction with fluorite elements, delivering exceptional image flatness across the entire field of view with superior chromatic aberration correction. This objective achieves the remarkable combination of 0.70 numerical aperture with 0.8-1.8mm working distance, providing resolution approaching that of standard objectives while maintaining extended clearance for thick specimens and micromanipulation. The integrated correction collar enables optimization for cover glass thickness from 0 to 1.6mm, compensating for spherical aberration introduced by varying cover glass thickness. Phase contrast microscopy enhances contrast in transparent, unstained specimens by converting phase shifts in light passing through the specimen into amplitude changes. The PH2 designation indicates this objective is optimized for use with 20x phase contrast condensers. The RMS thread ensures compatibility with Olympus BX, CKX, and IX series infinity corrected microscope systems. Excellent condition with flawless optics ensures optimal imaging performance for demanding research and laboratory applications.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp class=\"MsoNormal\" style=\"font-family: 'Segoe UI Emoji', sans-serif;\"\u003e\u003cspan style=\"font-weight: bold;\"\u003e🔎 Typical Applications\u003c\/span\u003e\u003c\/p\u003e\n\u003cul style=\"font-family: 'Segoe UI Emoji', sans-serif;\"\u003e\n\u003cli\u003eHigh-resolution long working distance phase contrast microscopy\u003c\/li\u003e\n\u003cli\u003eThick specimen and tissue culture imaging\u003c\/li\u003e\n\u003cli\u003eLive-cell imaging with micromanipulation\u003c\/li\u003e\n\u003cli\u003eCell biology and developmental biology\u003c\/li\u003e\n\u003cli\u003eResearch and advanced laboratory microscopy\u003c\/li\u003e\n\u003cli\u003eApplications requiring high NA with extended working distance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003cp class=\"MsoNormal\" style=\"font-family: 'Segoe UI Emoji', sans-serif;\"\u003e\u003cspan style=\"font-weight: bold;\"\u003e📊 Key Specifications\u003c\/span\u003e\u003c\/p\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; font-family: 'Segoe UI Emoji', sans-serif;\" border=\"1\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px; font-weight: bold;\"\u003eSpecification\u003c\/td\u003e\n\u003ctd style=\"padding: 8px; font-weight: bold;\"\u003eDetails\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px;\"\u003eModel Number\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eUCPLANFL N 20X\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px;\"\u003eCatalog Number\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eN6433800\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px;\"\u003eMagnification\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003e20x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px;\"\u003eOptical Design\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eUniversal plan fluorite (UCPLANFLN)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px;\"\u003ePhase Contrast\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003ePH2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px;\"\u003eNumerical Aperture (NA)\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003e0.70\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px;\"\u003eWorking Distance\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003e0.8-1.8mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px;\"\u003eCorrection Collar\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003e0-1.6mm cover glass thickness\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px;\"\u003eThread Type\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eRMS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px;\"\u003eCompatibility\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eOlympus BX, CKX \u0026amp; IX series (infinity corrected)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px;\"\u003eCondition\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eExcellent with flawless optics (pre-owned)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px;\"\u003ePrimary Advantage\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eHigh 0.70 NA with long working distance and correction collar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\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 welcomed and accepted.
