A microscope objective with dramatically improved chromatic aberration correction.
CFI Achromat Series objective lenses. Correction for chromatic aberration in this series has been dramatically improved and is now at the same level as the CFI Plan Achromat Series. These CFI Achromat objectives were also corrected for spherical aberration and coma and image flatness across the 22mm field of view has been drastically improved. The result: truly exceptional quality for this class of objectives.
