Mitutoyo Brightfield and Darkfield (BD) Infinity Corrected Objectives
  • 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 are available in standard Plan APO and Plan APO SL for extended working distances, and 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.
