Hi Thad,

You might get a good enough vacuum to coat a mirror but usely the 1st vacuum is a roughing stage and final vacuum comes in the form of a molecular pump of some sort. This is my hang up in finding one of the latter large enough. Then there is the electronics-Vacuum gauges, evaporative pwr source etc. Don`t trust glass for bell jar. Stainless steel is the prefered choice. Coating density can also be measured by transmission.

Keep in touch and good luck,
