Hi Charlie:

Edmunds does make telescope mirrors but my guess is you are talking about the shaving mirrors which are too thin and only approximate a parabolic shape. For a corrected optic there is only one curve for any given focal length, that is parabolic. Many for hyperbolic. Besides, by being thin they warp easily even from their own weight and the glue that holds them on.

Cheers,
-Rick
