Abstract:
A method of making a polymer layer having a selected index of refraction, the method using plasma enhanced chemical vapor deposition onto a substrate in a vacuum environment, comprising the steps of:(a) providing a monomer cross linkable into a polymer with said selected index of refraction;(b) making an evaporate by receiving a plurality of monomer particles as a spray into a flash evaporation housing, evaporating said monomer on an evaporation surface, and discharging said evaporate through an evaporate outlet;(c) making a monomer plasma from said evaporate by passing said evaporate proximate a glow discharge electrode and creating a glow discharge; and(d) cryocondensing said monomer plasma onto said substrate and crosslinking said monomer plasma thereon, forming said polymer layer having said selected index of refraction.
