Guided Discovery and Lesson Notes on Mirrors and Applications
... 1. Parallel rays far from the axis do converge at a point slightly closed to the mirror than the focal point: thus, the image formed by parallel rays is a disk instead of a point. 2. This deviation from an ideal point is called spherical aberration. 3. Spherical aberration can be eliminated using pa ...
