Abstract: An optical device includes a dielectric substrate and a cured resin coating adhered to the substrate. The resin coating includes an organic component and an inorganic component. A surface portion of the resin coating includes greater than about 60 at. % inorganic component and less than about 40 at. % organic component, an intermediate portion includes between about 10 at. % and about 60 at. % inorganic component, and between about 40 at. % and about 90 at. % inorganic component, and a bottom portion includes less than about 10 at. % inorganic component and greater than about 90 at. % organic component. The resin coating has improved hard coat properties and excellent adhesion to a dielectric.
