SN0322 14" f/4.7 (1.3" Pyrex)
Obsidian Optics Bench Test

           Comments: SN0333 - 14" f/4.7 POP - 5/13/04
   Optical diameter: 13.98"		Substrate: PA Pyrex 7740
Radius of curvature: 131.13"		Thickness: 1.3"
                f/D:  4.69		Diffraction disc: 0.000123589           

Mirror wavefront error < 1/20th wave PV across both diameters

Polish, diffraction edge, figure of revolution, and smoothness all excellent.
