Its 12.0mm working distance provides generous clearance for uneven, bulky, or delicate samples, reducing the risk of specimen and objective damage. Excellent flatness across a wide 26.5mm field number and high transmission from 400–700nm deliver sharp, high-contrast images, and the standard pupil position supports DIC and polarization. It is designed for use without a cover glass on Olympus BX and MX series microscopes.\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\u003eLong 12.0mm working distance for bulky, uneven, or delicate samples\u003c\/li\u003e\n  \u003cli\u003ePlan semi-apochromat (fluorite) correction for flat-field, high-contrast imaging\u003c\/li\u003e\n  \u003cli\u003e0.40 numerical aperture at 20x\u003c\/li\u003e\n  \u003cli\u003eWide 26.5mm field number\u003c\/li\u003e\n  \u003cli\u003eSuitable for brightfield, DIC, polarization, and fluorescence\u003c\/li\u003e\n  \u003cli\u003eHigh transmission from 400–700nm\u003c\/li\u003e\n  \u003cli\u003eDesigned for use without a cover glass\u003c\/li\u003e\n  \u003cli\u003eInfinity-corrected;
