Just a little eye candy to show some attempts to test one reference flat against another. The bottom perforated flat is already aluminized, and the top flat is double polished to show the interference lines.
I think the interference lines are too close together though. Comments welcome
The bottom picture just shows a red laser bouncing around the inside of the double polished flat. I thought it looked cool. 8)
