WebWhen the light is not monochromatic (not of a single wavelength), a sixth aberration is found in lenses but not in mirrors and is named chromatic aberration. Spherical Aberration In spherical aberration, rays of light from a point on the optical axis of a spherical lens do not all meet at the same image point. WebSpherical Aberration Spherical aberration (figure 2) occurs because paraxial rays passing through a lens are brought to a focus at a point which is further away from the lens than peripheral rays. In this situation a point object no longer gives a Figure 2. The origin of spherical aberration unique point image, but rather many image points

WebChromatic aberration, also known as color fringing, is a color distortion that creates an outline of unwanted color along the edges of objects in a photograph. Often, it appears … In optics, spherical aberration (SA) is a type of aberration found in optical systems that have elements with spherical surfaces. Lenses and curved mirrors are prime examples, because this shape is easier to manufacture. Light rays that strike a spherical surface off-centre are refracted or reflected more or less than those that strike close to the centre.
