I would be interested in tapping the collective wisdom of the list in regards to
determining when an optical surface is considered polished.
I have been inspecting the surface with a microscope. When I cannot see any pits
out to the edge with the microscope, I consider the surface polished. More
recently I have also been shining a light at the surface to see if the light
passes through or is reflected from the surface. If the light passes through, I
consider the surface pretty good. I always back it up with the microscope
however.
Any other suggestions? I would also be interested in how professional shops make
the determination as to surface quality.
