OLYMPUS UPLANFLN 4X PHL PHASE CONTRAST OBJECTIVE Achieve wide-field phase contrast imaging with PHL (Phase Low) configuration, featuring: 🔬 4x magnification with PHL phase contrast for specialized low-magnification imaging 🌈 Plan fluorite (UPLANFLN) optical design for superior flatness and color correction 📏 17mm working distance for excellent specimen clearance 🎯 0.13 numerical aperture optimized for low-magnification phase contrast 🔧 RMS thread compatible with BX & IX series microscopes ⭐ Excellent condition with pristine optical performance 🔧 Product Description The Olympus UPLANFLN 4X PHL phase contrast objective is specifically engineered for wide-field phase contrast microscopy with specialized PHL (Phase Low) configuration. The plan fluorite (UPLANFLN) optical design combines plan (flat-field) correction with fluorite elements, delivering exceptional image flatness across the entire field of view with superior chromatic aberration correction. The PHL designation indicates this objective uses a specialized phase ring configuration optimized for low-magnification phase contrast applications, providing enhanced contrast characteristics compared to standard phase contrast objectives. Phase contrast microscopy enhances contrast in transparent, unstained specimens by converting phase shifts in light passing through the specimen into amplitude changes, making cellular structures visible without staining. At 4x magnification, this objective provides a wide field of view ideal for scanning large areas and low-magnification phase contrast imaging. The 0.13 numerical aperture is optimized for low-magnification applications, providing excellent depth of field. The generous 17mm working distance provides ample clearance for specimen manipulation and accommodates thicker specimens and culture vessels. The RMS thread ensures compatibility with Olympus BX and IX series infinity corrected microscope systems. Excellent condition ensures optimal optical performance and reliable operation for demanding research, clinical, and laboratory applications. 🔎 Typical Applications Wide-field phase contrast microscopy with PHL configuration Live-cell imaging and tissue culture observation Cell biology and developmental biology Clinical and diagnostic microscopy Large-area transparent specimen imaging Research and advanced laboratory microscopy 📊 Key Specifications Specification Details Model Number UPLANFLN 4X PHL Magnification 4x Optical Design Plan fluorite (UPLANFLN) Phase Contrast PHL (Phase Low) Numerical Aperture (NA) 0.13 Working Distance 17mm Thread Type RMS Compatibility Olympus BX & IX series microscopes Condition Excellent (pre-owned) Primary Advantage PHL phase configuration with plan fluorite optics and 17mm WD University purchase orders are welcomed and accepted.
