| apochromatic lens | A compound lens designed to correct both spherical and chromatic aberrations. (05 Mar 2000) |

| apochromatic objective | <microscopy> A lens system whose secondary chromatic aberrations have been substantially reduced. It is designed to provide the same focal length for three wavelengths and freedom from spherical aberration for two wavelengths of light. The magnification can still vary with wavelength in which case a compensating eyepieces used to cancel the coloured fringes. (05 Aug 1998) |
| plan apochromatic objective lens | <physics> A modern, high-numerical aperture microscope objective lens designed with high degrees of corrections for various aberrations. It is corrected for spherical aberration in four wavelengths (dark blue, blue, green, and red), for chromatic aberration in more than these four wavelengths, and for flatness of field. A single Plan Apo objective may contain as many as 11 lens elements. (05 Aug 1998) |

| semi-apochromatic objective | <microscopy> A compromise, in the correction for chromatic and spherical aberration, between achromatic and apochromatic objectives, such as a fluorite objective. (05 Aug 1998) |

| apochromatic |
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.
