Quote:A very lazy but very effective solution to fixing issues based on the coverglass is to complete the design then vary every radius of curvature with the new coverglass thickness.  The optical path is very similar but the balance of astigmatism and spherical must be adjusted - often the optical design software will "smash" the new aberration and recover 90%+ of the old performance.
Do you think it can also work for very wide angles such as Biogon 21/2.8 or even Hologon 16/8 ?
