Medical Definition of Flourite objectives
1.
Microscope objective lenses considerably better corrected than achromats but not quite as well corrected as the apochromats. By using fluorite crystals (which have lower dispersion) in place of some of the glass elements, a fluorite objective corrects for spherical aberrations in three wavelengths at considerably lower cost than the apochromatis.
