Best fit radius
Best fit radius
(OP)
I am looking for an equation that will solve for the best fit weighted average radius for a conic surface. This is to correlate with our interferometer measurements. Currently we do this by a brute force method creating sag tables of the conic surface and a spherical surface and use solver to minimize the RMS error. I assume there is a more eloquent way to do this however. Thank you for your help.

RE: Best fit radius
For a given Radius, Conic, and Aperture a best fit radius should be able to be derived. Before figuring it out myself I was hoping someone had already done it. If not I'll figure it out and post here. Thanks.
