ZEISS FLUAR 20X HIGH-TRANSMISSION FLUORESCENCE OBJECTIVE Maximize fluorescence signal collection and photon efficiency with this specialized high-performance objective, featuring: 💡 Optimized for maximum light transmission and photon collection in fluorescence applications 🔬 20x magnification with 0.75 numerical aperture for high-resolution fluorescence imaging 📏 0.60mm working distance for standard preparations 🔧 RMS thread mount (M27 adapter available upon request) ⭐ Excellent pre-owned condition with flawless optical performance 🔧 Product Description The Zeiss Fluar 20x objective represents specialized optical engineering for demanding fluorescence microscopy applications where signal intensity and photon collection efficiency are critical. Manufactured from proprietary low-fluorescence glass formulations, Fluar objectives minimize autofluorescence while maximizing transmission across UV, visible, and near-infrared wavelengths. At 20x magnification with 0.75 numerical aperture, this objective delivers exceptional resolution and light-gathering capability for high-resolution fluorescence imaging of cellular structures, fluorescent labels, and subcellular organelles. The high NA enables superior photon collection efficiency essential for weak fluorescence signals and quantitative imaging applications. The 0.60mm working distance accommodates standard microscope slides with #1.5 coverslips. The RMS thread mount ensures compatibility with a wide range of microscope platforms, and an M27 adapter is available upon request for Zeiss infinity-corrected systems. Fluar objectives are particularly valued in quantitative fluorescence applications including calcium imaging, FRET analysis, multi-color immunofluorescence, and live-cell imaging where consistent photon collection and minimal optical aberrations are essential for accurate measurements and high signal-to-noise ratios. 🔎 Typical Applications Quantitative fluorescence microscopy and photometry Multi-color immunofluorescence imaging of cells and tissues Live-cell calcium imaging and ion indicator studies FRET (Förster Resonance Energy Transfer) analysis High-resolution confocal and multiphoton microscopy Weak fluorescence signal detection and quantification 📊 Key Specifications Specification Details Catalog Number 440145-9901 Magnification 20x Numerical Aperture (NA) 0.75 Working Distance 0.60mm Optical Design Fluar (high-transmission fluorescence) Correction Infinity-corrected Thread Mount RMS (M27 adapter available upon request) Condition Excellent with flawless optics (pre-owned) Primary Advantage Maximum photon collection for quantitative fluorescence University purchase orders are welcomed and accepted.
