WebMay 25, 2024 · The best optics limit aberration as much as possible to provide a clear, accurate image. One example of aberration is chromatic aberration, which occurs when lenses in an optic incorrectly refract different colors of light. The result of this aberration is differing focal points and a distorted image. WebGeometrical Distortion. Distortion is an aberration commonly seen in stereoscopic microscopes, and is manifested by changes in the shape of an image rather than the sharpness or color spectrum. The two most … WebOptical aberrations are deviations from a perfect, mathematical model. It is important to note that they are not caused by any physical, optical, or mechanical flaws. Rather, they can be caused by the lens shape itself, or the placement of optical elements within a system, due to the wave nature of light. sims 4 teen pregnancy download
