Optical element containing an optical spacer

Disclosed is an optical element containing a rough surface having a roughness average equal to at least 5 micrometers wherein the rough surface contains at least two roughness populations in which the roughness average of the at least two populations varies by at least 8 micrometers. The invention p...

More Information
Summary:Disclosed is an optical element containing a rough surface having a roughness average equal to at least 5 micrometers wherein the rough surface contains at least two roughness populations in which the roughness average of the at least two populations varies by at least 8 micrometers. The invention provides an optical element containing an integral optical spacer while simultaneously providing scratch and impact resistance.
