Product Details

The Brightfield and Darkfield (BD) Infinity Corrected Objectives lenses deliver diffraction-limited performance across the entire visible spectrum. Its advanced multi-element optical design, combined with optimized coatings and infinity correction, minimizes aberrations while maximizing optical transmission for exceptional image quality. The lenses are optimized for both brightfield and darkfield optical configuration that enables coaxial brightfield and darkfield illumination, making them well suited for high-contrast imaging and inspection applications.
Thanks to their long working distance and infinity-corrected design, these objective lenses can also be integrated into laser systems for coaxial observation and visible laser focusing. They enable precise microscopic observation and laser focusing from a comfortable working distance.
These objective lenses are ideal for applications in microscopy, machine vision, laser systems, and precision optical inspection where superior resolution and image quality are critical.
 

Key technical features include:

  • High numerical aperture (NA) 
  • High-resolution with diffraction-limited performance
  • Ideal for Brightfield and Darkfield Microscopy Applications
  • Apochromatic aberration correction for accurate color reproduction and minimized color fringing
  • Plan Apochromatic Design
  • Standard RMS threading for compatibility with conventional microscopes and optical mounts

Applications

  • Microscopy
  • Imaging
  • Machine vision
  • Precise optical inspection
  • Metrology
