Are aspheric surfaces free of aberration? x4I!f)8Q
pG#tMec
The conic aspherics (e.g., paraboloid, ellipsoid, hyperboloid, and the sphere) have b* n3Fej
no spherical aberration if the object point is at one focal point and the [ P
&B
image is at the other. But if we depart from this condition we definitely /x??J4r0
do get spherical aberration. !-lI<$S:
