CHROMATIC ABERRATION Meaning and
Definition
-
Chromatic aberration, in the realm of optics, refers to an optical phenomenon where different colors of light do not converge or focus at the same point after passing through a lens or other optical system. This results in a blurred or distorted image, with color fringing or halos around the edges of objects.
When white light, which consists of various colors with different wavelengths, passes through a lens, each color refracts or bends at a slightly different angle. Consequently, the focal point for each color varies, causing them to land at different positions and resulting in image distortion. Chromatic aberration occurs due to the variation in the refractive index of the lens material for different wavelengths. This deviation is more pronounced in lenses with higher magnification power or wider angles of view.
There are two types of chromatic aberration: axial and transverse. Axial chromatic aberration occurs when different colors have their focal points at different distances along the lens axis, leading to the image plane not being achieved at one point. Transverse chromatic aberration, also known as lateral or color fringing, manifests as colored edges around objects, as different colors are displaced relative to one another on the image plane.
To mitigate chromatic aberration, various techniques are employed in lens design, such as using low-dispersion glass elements, aspherical lenses, and lens coatings. Post-processing tools and software can also be employed to correct chromatic aberration and enhance image quality.

Etymology of CHROMATIC ABERRATION
The word "chromatic aberration" originates from the combination of two terms: "chromatic" and "aberration".
1. "Chromatic": The term "chromatic" derives from the Greek word "khroma" (χρώμα), which means "color". It entered the English language through the Latin word "chromaticus", denoting "pertaining to color". The term is commonly used in the context of various fields, including physics, optics, and visual arts, to refer to anything related to colors.
2. "Aberration": The word "aberration" comes from the Latin word "aberratio", which means "a wandering away". It is derived from the verb "aberrare", combining "ab" (away) and "errare" (to wander). "Aberration" generally describes a departure from what is considered normal, correct, or expected.
