Optical Coatings By Conveyorized Atmospheric Chemical Vapor Deposition (CVD)

Thin films. We're considering their importance and use in great quantity. But how do you get thin films?- especially in great quantity, big sizes, high quality and still cheap? "Thin" , where coatings are concerned is often defined as less than one mil or sg. "Thick" films are more than a mil or so. For optical coatings we're often in the tenth micron (1000 A, 0.004 mil) range or less.
