Aplanatism
Definition
The property or geometric condition of an optical system to simultaneously correct and eliminate both spherical aberration and coma aberration for a given point-like object. This physical phenomenon is achieved through strict compliance with Abbe's sine condition, ensuring the formation of exceptionally sharp and perfectly stigmatic images in the vicinity of the main optical axis.
