Part of Olympus’s \u003cb\u003eLong Working Distance Plan Semi-Apochromatic series\u003c\/b\u003e, this lens bridges the gap between detailed imaging and practical sample access — especially when working through thicker sample holders or vessels such as dishes, slides, or culture chambers.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eWith \u003cb\u003e20× magnification and a numerical aperture (NA) of 0.70\u003c\/b\u003e, this objective delivers a compelling combination of \u003cb\u003estrong resolution and excellent light collection\u003c\/b\u003e, ideal for brightfield, fluorescence, and multi-modal imaging workflows. The \u003cb\u003ePlan Semi-Apochromat optical design\u003c\/b\u003e minimizes common optical distortions such as chromatic and spherical aberrations, helping produce sharper, high-contrast images that remain accurate from center to edge.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eA defining benefit of this objective is its \u003cb\u003elong working distance (approximately 0.80–1.80 mm)\u003c\/b\u003e — providing space between the lens and specimen that allows researchers to image through thicker media without needing immersion. This makes the UCPLFLN20X2 particularly well suited for use with \u003cb\u003einverted microscope configurations\u003c\/b\u003e, perfusion systems, live-cell environments, and any application where direct access above the sample is limited or requires additional tools.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eDesigned for compatibility with standard \u003cb\u003eRMS-threaded upright microscopy systems\u003c\/b\u003e, this objective integrates easily into existing research or clinical setups, making it a reliable choice for laboratories engaged in demanding imaging workflows across disciplines.\u003c\/p\u003e\n\u003cdiv class=\"MsoNormal\" align=\"center\" style=\"text-align: center;\"\u003e\u003chr size=\"2\" width=\"100%\" align=\"center\"\u003e\u003c\/div\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003e\u003cspan style=\"font-family: 'Segoe UI Emoji',sans-serif;
