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. WebAn optical aberration is a property of an optical system that causes the light that goes through it to spread rather than to focus on a point. In other words, aberrations are imperfections of optical systems. They are not caused by defects in the making of devices but rather because of their physical conditions. how many elements occur naturally in natureWebOptical imaging systems can exhibit various kinds of aberrations, i.e., reductions of image quality which can be analyzed based on geometrical optics.

Chromosomal Aberrations • Can be caused either by • non-disjunction (failure of whole chromosomes to separate during meiosis) • translocation (bits of chromosomes that are re-attached to other chromosomes). Individuals end up either with extra whole or bits of chromosomes or with missingwhole or bits of chromosomes.

WebSpherical aberration. A perfect lens (top) focuses all incoming rays to a point on the Optical axis. In spherical aberration (Bottom) peripheral rays are focused more tightly than central rays. There are numerous higher-order aberrations, of which only spherical aberration, coma and trefoil are of clinical interest.
