Microscope objectives with superior image flatness and color reproduction.

CFI plan apochromat series objective lenses for phase contrast microscopy. Correction for chromatic aberration has been improved and now extends across the entire visible spectrum to include the violet wavelength. High Numerical Apertures with longer working distances, comprehensive aberration correction, and superior flatness of field of view across 25mm make Nikon's CFI Plan Apochromat series for phase contrast microscopy ideal for the most demanding research projects. These objectives can also be used effectively for DIC observation.
