Then don't! However, there are a few that have maksutovs that can testify to
the super smoothness that can be realized with spherical surfaces. I have
several maksutovs made by the late Max Bray that are very smooth indeed.



If you are limited by the traditional mechanical means of applying the
deforming forces then you might be correct. There are many ways to apply
local forces to deform glass. I can think of a couple-for example, piezo
actuators or local heating using ultrasonic sound generation. If one starts
out believing something cannot be done, then it probably won't. Just because
one shows one can't get from here to there by a particular path doesn't mean
there isn't some other path that will lead from here to there.
