Reflection - Spherical aberration Walker, Physics, 4thed., pg. 914The preceding slides only apply to rays which are near the principle axis of the mirror. Rays farther from axis have different focal point. This gives blurred image and is known as spherical aberration.This can be fixed by….1)Restrict incoming rays to only those near axis.2)Use parabolic mirror which has one focal point for aller
