chromatic aberration: see aberration aberration, in optics, condition that causes a blurring and loss of clearness in the images produced by lenses or mirrors. Of the many types of aberration, the two most significant to the lens maker are spherical and chromatic. ..... Click the link for more information. , in optics. chromatic aberrationFringes of color at the edges of objects in a photograph due to the inability of the camera lens to deal with all wavelengths of light equally. High-quality lenses that use multiple elements generally diminish chromatic aberration. See purple fringing and lens flare. Chromatic aberration The type of error in an optical system in which the formation of a series of colored images occurs, even though only white light enters the system. Chromatic aberrations are caused by the fact that the refraction law determining the path of light through an optical system contains the refractive index, which is a function of wavelength. Thus the image position and the magnification of an optical system are not necessarily the same for all wavelengths, nor are the aberrations the same for all wavelengths. See Aberration (optics), Refraction of waves |

6L IS USM, both of which are L (luxury)-series lenses incorporating a high-performance Image Stabilizer, feature optical systems utilizing special optical materials such as fluorite to correct chromatic aberrations, making possible high-resolution, high-contrast shooting performance. With Geo, optical problems such as lateral chromatic aberrations, optical distortion, and three-panel misconvergence can be corrected electronically, eliminating the need for more expensive optical and mechanical solutions. nbsp;element and two UD (ultra low dispersion) elements thoroughly suppress chromatic aberrations for crisp photos throughout the entire focal range. |
