Definitions from the WebOptical AberrationDefinitionOptical aberration refers to deviations or distortions that occur in the formation of an image by an optical system. It occurs due to various factors such as lens imperfections, refraction, or light diffraction. UsageOptical aberration can affect the clarity, sharpness, and color accuracy of an image captured by cameras, telescopes, and other optical devices. It is an important consideration in the field of optics and is actively studied and corrected in lens designs. SensesSense 1: Chromatic AberrationIn optics, chromatic aberration is a type of optical aberration that causes different colors to focus at different points. It results in color fringes or blurring around the edges of an image. This can be reduced using specialized lenses or software. Example sentence: The photographer noticed slight chromatic aberration in the corners of the photograph, causing the edges of the subject to appear slightly blurred. Sense 2: Spherical AberrationSpherical aberration occurs when light rays passing through the outer or inner portions of a lens do not converge at a single point, resulting in a blurred or distorted image. This can be corrected by using multiple lens elements or aspherical lenses. Example sentence: The telescope's images had significant spherical aberration, causing the stars to appear as blurry blobs rather than sharp points of light. Sense 3: Coma AberrationComa aberration causes off-axis light rays to appear as distorted comet-like shapes. It often occurs in astrophotography or when using large aperture lenses. Correcting coma aberration can lead to improved sharpness and quality of the captured images. Example sentence: With the new lens, the photographer was able to capture stunning images of stars without any noticeable coma aberration.
