Somatische aberration
WebChromatic aberration, also known as “dispersion”, “purple fringing”, or “color fringing,” is a frequent lens problem that arises when colors are refracted (bent) wrongly by the lens. This causes a mismatch at the focus point where the colors do not mix the way they are supposed to. Remember that the focal plane is the point of focus ... WebThe aberrations and properties corresponding to these Zernike terms are shown in Table IV. Writing the wavefront expansion in terms of field-independent wavefront aberration …

WebEffects from various aberrations in a lens design are ultimately seen in performance and affect modulation transfer function (MTF), spot size, telecentricity, depth of field (DOF), and others. Aberration theory is an abstract and complex subject. However, understanding how aberrations affect performance is important for success with an application.

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. This deviation reduces the quality of …
WebLens Aberration. In optics, aberration is a property of optical systems such as lenses that results in light being spread out over some region of space rather than being focused to a point. An image-forming optical system with aberration will produce an image that is not sharp. Aberration can be caused due to a variety of reasons such as lens ...

Ideally, all the waves converge at the same point. Aberrations occur when light waves converge at different points.
