The Plan-Neofluar optical design provides excellent flat-field correction and high light throughput, making it well-suited for both brightfield and phase contrast imaging. With a 0.50 numerical aperture and 2mm working distance, this objective delivers sharp, high-contrast images of unstained living cells and transparent specimens without the need for chemical fixation or staining. The PH2 phase ring is matched for use with standard Zeiss PH2 condenser annuli, ensuring optimal phase contrast alignment. This unit is in light use condition with flawless optics — a reliable, cost-effective upgrade or replacement for your Zeiss system.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003cp\u003e\u003cstrong\u003e🔎 Typical Applications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eLive cell imaging and cell culture monitoring\u003c\/li\u003e\n  \u003cli\u003eMicrobiology and bacteriology\u003c\/li\u003e\n  \u003cli\u003eHistology and tissue section examination\u003c\/li\u003e\n  \u003cli\u003eEmbryology and developmental biology\u003c\/li\u003e\n  \u003cli\u003eRoutine clinical and research microscopy\u003c\/li\u003e\n  \u003cli\u003eTeaching and educational laboratory use\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cp\u003e\u003cstrong\u003e📊 Key Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"width:100%; border-collapse: collapse;\"\u003e\n  \u003ctr style=\"background-color:#f2f2f2;\"\u003e\n\u003cth style=\"text-align:left; padding:6px; border:1px solid #ddd;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"text-align:left; padding:6px; border:1px solid #ddd;\"\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:6px; border:1px solid #ddd;\"\u003eMagnification\u003c\/td\u003e\n\u003ctd style=\"padding:6px; border:1px solid #ddd;\"\u003e20X\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:6px; border:1px solid #ddd;\"\u003eObjective Type\u003c\/td\u003e\n\u003ctd style=\"padding:6px; border:1px solid #ddd;\"\u003ePlan-Neofluar\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:6px; border:1px solid #ddd;\"\u003ePhase Contrast\u003c\/td\u003e\n\u003ctd style=\"padding:6px; border:1px solid #ddd;\"\u003ePH2\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:6px; border:1px solid #ddd;\"\u003eCorrection\u003c\/td\u003e\n\u003ctd style=\"padding:6px; border:1px solid #ddd;\"\u003eInfinity Corrected\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:6px; border:1px solid #ddd;\"\u003eNumerical Aperture (NA)\u003c\/td\u003e\n\u003ctd style=\"padding:6px; border:1px solid #ddd;\"\u003e0.50\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:6px; border:1px solid #ddd;\"\u003eWorking Distance\u003c\/td\u003e\n\u003ctd style=\"padding:6px; border:1px solid #ddd;\"\u003e2mm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:6px; border:1px solid #ddd;\"\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd style=\"padding:6px; border:1px solid #ddd;\"\u003eGermany\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:6px; border:1px solid #ddd;\"\u003eCondition\u003c\/td\u003e\n\u003ctd style=\"padding:6px; border:1px solid #ddd;\"\u003eLight Use — Flawless Optics\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:6px; border:1px solid #ddd;\"\u003eSKU\u003c\/td\u003e\n\u003ctd style=\"padding:6px; border:1px solid #ddd;\"\u003e1004-989\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003chr\u003e\n\n\u003cp\u003e\u003cem\u003eUniversity and institutional purchase orders are welcome.
