Its correction collar compensates for cover glass and vessel bottom thicknesses from 0.5 to 1.5mm, allowing high-magnification phase contrast imaging through culture dishes, flasks, and well plates. The DLL (Dark Low Low) phase ring provides a dark-contrast phase image with reduced halo, revealing fine detail in live, unstained cells, while fluorite optics offer high transmission for fluorescence work.\u003c\/p\u003e\n\n\u003ch3\u003eCondition\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eCondition:\u003c\/strong\u003e Refurbished\/Used (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\u003eExtra-long working distance (ELWD): 1.1–2.1mm\u003c\/li\u003e\n  \u003cli\u003eCorrection collar for cover glass and vessel bottoms from 0.5 to 1.5mm\u003c\/li\u003e\n  \u003cli\u003eDLL (Dark Low Low) Ph2 phase contrast for high-contrast, low-halo imaging of live cells\u003c\/li\u003e\n  \u003cli\u003ePlan fluorite correction for flat-field, high-transmission imaging\u003c\/li\u003e\n  \u003cli\u003eHigh 0.70 numerical aperture at 60x\u003c\/li\u003e\n  \u003cli\u003eSuitable for phase contrast, brightfield, and fluorescence\u003c\/li\u003e\n  \u003cli\u003eNikon CFI60 infinity-corrected optics\u003c\/li\u003e\n  \u003cli\u003eM25 objective thread\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-magnification phase contrast imaging of live cells\u003c\/li\u003e\n  \u003cli\u003eImaging through culture dishes, flasks, and well plates\u003c\/li\u003e\n  \u003cli\u003eCombined phase contrast and fluorescence imaging\u003c\/li\u003e\n  \u003cli\u003eTissue culture and cell biology\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"border-collapse: collapse;
