ASPHERICAL Meaning and
Definition
-
Aspherical is an adjective used to describe a three-dimensional shape, typically referring to a surface or lens, that is not perfectly round or symmetrical in nature. The term "aspherical" is derived from the word "sphere," denoting a solid geometric figure with all points equidistant from a common center.
In the context of optics, an aspherical lens refers to a lens that deviates from the shape of a perfect sphere or has a non-uniform curvature. Unlike spherical lenses that have a consistent curvature across their surface, aspherical lenses have different curvatures at different points which allow for better correction of certain optical aberrations. By introducing non-uniform shapes, they can help minimize image distortion, reducing the occurrence of spherical and chromatic aberrations, coma, and other imperfections that may occur with spherical lenses. Aspherical lenses are widely used in various optical systems to improve lens efficiency, increase image quality, and reduce unwanted visual artifacts.
Beyond optics, the term aspherical can also be applied to any three-dimensional object or surface that does not conform to a perfect sphere's shape, such as irregularly shaped objects or structures. In this broader sense, aspherical pertains to any object that deviates from spherical symmetry, exhibiting a non-uniform or distorted form.
Overall, aspherical refers to a shape or lens that diverges from the ideal spherical curvature, often employed in optics to enhance optical performance and image quality.
Common Misspellings for ASPHERICAL
Etymology of ASPHERICAL
The word "aspherical" is derived from the combination of the prefix "a-" meaning "without" or "not" and the adjective "spherical", which ultimately traces back to the Latin word "sphaericus". The etymology of "sphaericus" can be connected to the Greek word "sphaîra", meaning "globe" or "ball". Over time, "sphaîra" evolved into "sphaericus" in Latin, and later influenced the formation of the English term "spherical". Hence, "aspherical" refers to something that lacks the shape or properties of a sphere.
