Have any of you had any experience in obtaining "optical quality" glass for
your print frames?

Yes...but at a high cost. I required it for exposing materials used for a
photochemical milling application. When you talk about Optical Quality, you
must keep in mind that this term is often misused. My material cost me
about $600.00. This was because of its optical flatness and an almost
perfect surface.
