🔧 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
