Optical finish for acrylic -- vapor polishing and other techniques (2013x20)

Data de estreia: Jul 22, 2013

I needed to polish two acrylic lenses that were made on a CNC lathe to the best possible finish (hopefully, optical quality). I made some test coupons and tried three different polishing techniques on three different surfaces to see which combination of techniques would yield the best results. The winner was clearly 2000 grit sandpaper followed by Novus No.2 polish. Vapor polishing: http://www.youtube.com/watch?v=bduno3eafcc
