Are aspheric surfaces free of aberration? RgFpc*.T
YdvXp/P:|
The conic aspherics (e.g., paraboloid, ellipsoid, hyperboloid, and the sphere) have "Ke_dM
no spherical aberration if the object point is at one focal point and the (:~_#BA
image is at the other. But if we depart from this condition we definitely zQ<&[Tuwa
do get spherical aberration. u*iqwm.
