Product Family Description

  • Ideal for Brightfield and Darkfield Microscopy Applications
  • Long Working Distances and High Numerical Apertures
  • Plan Apochromat Design

Mitutoyo Brightfield and Darkfield (BD) Infinity Corrected Objectives offer long working distances with high numerical apertures. The high-quality plan apochromatic design allows these objectives to maintain high numerical apertures and contrast while correcting chromatic aberration in the visible wavelength region. These objectives feature M40 x 36TPI mounting threads. Mitutoyo Brightfield and Darkfield (BD) Infinity Corrected Objectives are optimized for both brightfield and darkfield illumination for applications including surface inspection and advanced life science microscopy.

Note: If compatible tube lens MT-1 (#54-774) or MT-2 (#56-863) are used to build a custom setup, an additional darkfield stop is needed to use darkfield illumination.
