Origin and Evolution of afocal

First Known Use: 1950 year
Language of Origin: English
Story behind the word: The word 'afocal' originated from the combination of the prefix 'a-' meaning 'without' or 'not' and the word 'focal' referring to a point of convergence or focus.
Evolution of the word: The term 'afocal' has primarily been used in the field of optics to describe a lens system that does not have a specific focal length. Over time, it has also been adopted in other disciplines to denote a lack of a specific focal point or direction, broadening its usage beyond its original optical context.
