Apochromatic is a description of a photographic or other lens having a high degree of color correction. Chromatic aberration is the phenomenon of different colors focusing at different distances from a lens (see the article for an excellent illustration). In photography, it leads to fuzzy images, and to color fringes at high-contrast edges, like an edge between black and white. Astronomers face similar problems, particularly with telescopes that use lenses rather than mirrors. ...

| apochromatic lens |
Similar to the achromatic lens, the apochromatic lens corrects for three colors (red, blue and green), greatly reducing the blur caused by the colors uncorrected by the achromat lens.In addition the lens is better corrected for spherical aberration.
