   Aberration
   A defect in an optical instrument or system. There are several types of abberation, descriptions of a few follow: Chromatic abberation occurs in lenses and is caused by different wavelengths of light focusing at different points and results in coloured fringes around objects; Spherical abberation is caused when the innner and outer parts of a lens or mirror have different focal lengths and results in blurred images; Astigmatism is where an image is focused into a cross or ellipse and is caused by optics that are not a uniform, spherical shape; Coma causes elongated or fanned images toward the edge of the field of view.

   Aberration
   Aberration: (1) A deviation or irregularity. For example, a chromosome aberration is a deviation from the normal chromosome number or the normal chromosome structure. In this sense, aberration is also synonymous with deflection, departure, divergence, diversion, turning. (2) A mental aberration is a significant deviation from normal mental activity ...

    Aberration
    (1) Something that prevents light from being brought into sharp focus, disenabling the formation of a clear image. (2) Lens flaw - the inability of a lens to reproduce an accurate, focused, sharp image. Aberration in simple lenses is sub-categorized into seven types: Astigmatism - lines in some directions are focused less sharply than lines in othe ...

12. 
    aberration
    Departure from normal; in microscopy two common forms of optical aberration cause problems, spherical aberration in which there is distortion of the image of the magnified object and chromatic aberration that leads to coloured fringes -a consequence of the unequal refraction of light of different wavelength.
