Anastigmatism
Definition
An ideal optical property or characteristic of a lens or mirror system being completely free from astigmatism; the absence of asymmetric focusing distortions, allowing oblique light rays passing through the system to converge into a single precise focal point. This structural phenomenon guarantees uniform sharpness and an exceptional flatness of the image across the entire surface of the projection plane, eliminating marginal blurring.
