ZEISS FLUAR 10X HIGH-TRANSMISSION FLUORESCENCE OBJECTIVE Maximize fluorescence signal collection and photon efficiency at mid-magnification with this specialized high-performance objective, featuring: π‘ Optimized for maximum light transmission and photon collection in fluorescence applications π¬ 10x magnification with 0.50 numerical aperture for high-resolution fluorescence imaging π 1.6mm working distance for standard preparations π§ M27 thread mount for Zeiss infinity-corrected microscope systems β Excellent pre-owned condition with flawless optical performance π§ Product Description The Zeiss Fluar 10x objective represents specialized optical engineering for demanding fluorescence microscopy applications where signal intensity and photon collection efficiency are critical at mid-magnification. Manufactured from proprietary low-fluorescence glass formulations, Fluar objectives minimize autofluorescence while maximizing transmission across UV, visible, and near-infrared wavelengths. At 10x magnification with 0.50 numerical aperture, this objective delivers exceptional light-gathering capability and resolution for fluorescence imaging while maintaining the wide field of view essential for specimen overview and navigation. The high NA for a 10x objective enables superior photon collection efficiency essential for weak fluorescence signals and quantitative imaging applications. The 1.6mm working distance accommodates standard microscope slides with #1.5 coverslips. The M27 thread mount ensures compatibility with Zeiss Axio and other infinity-corrected platforms. 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 at mid-magnification. π Typical Applications Quantitative fluorescence microscopy and photometry at mid-magnification Multi-color immunofluorescence imaging and cell biology Live-cell calcium imaging and ion indicator studies FRET (FΓΆrster Resonance Energy Transfer) analysis High-resolution confocal and multiphoton microscopy Weak fluorescence signal detection and quantification π Key Specifications Specification Details Catalog Number 420140 Magnification 10x Numerical Aperture (NA) 0.50 Working Distance 1.6mm Optical Design Fluar (high-transmission fluorescence) Correction Infinity-corrected Thread Mount M27 (Zeiss standard) Condition Excellent with flawless optics (pre-owned) Primary Advantage Maximum photon collection for quantitative fluorescence at 10x University purchase orders are welcomed and accepted.
