Are aspheric surfaces free of aberration? w!^~<{ Kz

The conic aspherics (e.g., paraboloid, ellipsoid, hyperboloid, and the sphere) have zU5Hb2a
no spherical aberration if the object point is at one focal point and the (K..k-o`.
image is at the other. But if we depart from this condition we definitely vXj <
do get spherical aberration. L5fuM]G`
