OLYMPUS LUCPLANFL N 20X LONG WORKING DISTANCE PHASE CONTRAST OBJECTIVE WITH CORRECTION COLLAR Achieve exceptional long working distance phase contrast imaging with correction collar, featuring: π 6.6-7.8mm long working distance for thick specimens and culture vessels π§ Correction collar for cover glass thickness optimization (0-1.6mm) π¬ 20x magnification with phase contrast for detailed cellular visualization π― 0.45 numerical aperture for excellent resolution with extended WD π LUCPLANFLN optics for superior flatness and color correction β¨ Factory-new condition with pristine optical performance π§ Product Description The Olympus LUCPLANFL N 20X long working distance phase contrast objective is specifically engineered for high-resolution phase contrast microscopy with exceptional working distance and correction collar capability. The LUCPLANFLN (Long Universal Plan Fluorite) optical design combines plan (flat-field) correction with fluorite elements and extended working distance, delivering exceptional image flatness across the entire field of view with superior chromatic aberration correction. 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. This ensures optimal image quality across different specimen preparation methods. At 0.45 numerical aperture with 6.6-7.8mm working distance, this objective provides excellent resolution while maintaining exceptional clearance for thick specimens, culture vessels, and micromanipulation. Phase contrast microscopy enhances contrast in transparent, unstained specimens by converting phase shifts in light passing through the specimen into amplitude changes. The RMS thread ensures compatibility with Olympus BX, CKX, and IX series infinity corrected microscope systems. Factory-new condition ensures optimal imaging performance for demanding research and laboratory applications. π Typical Applications Long working distance phase contrast microscopy Thick specimen and tissue culture imaging Live-cell imaging with micromanipulation Cell biology and developmental biology Research and advanced laboratory microscopy Applications requiring cover glass thickness correction π Key Specifications Specification Details Model Number LUCPLANFL N 20X Catalog Number 1-U2C375 Magnification 20x Optical Design Long universal plan fluorite (LUCPLANFLN) Phase Contrast Yes Numerical Aperture (NA) 0.45 Working Distance 6.6-7.8mm Correction Collar 0-1.6mm cover glass thickness Thread Type RMS Compatibility Olympus BX, CKX & IX series (infinity corrected) Condition Factory-new Primary Advantage Long working distance with correction collar for versatile applications University purchase orders are welcomed and accepted.
