We use Ultra Optics M/R III and are coating Hi Index 1.60 and 1.67 as well as poly. We see twice as many specs on the Hi Index / high curve lenses (sun wear) as on our poly lenses with lower curves. We use separate machines and different coating for Hi Index as opposed to the poly coating. Other than that the machines are set up the same and to factory specifications. The specs appear to be small bubbles or bubbles that have popped. They are pretty random. We have a clean room environment. Does anyone have any suggestions for what settings I can try adjusting? Thanks.
