Abstract
According to at least one feature of the present disclosure, a method of forming a film of an optical element, includes: positioning a substantially transparent lens in a reactor chamber, wherein the lens defines a curved surface; exposing the lens to a first precursor comprising one of lanthanum or gadolinium such that the first precursor is deposited on the curved surface of the lens; exposing the first precursor on the curved surface to a first oxidizer such that the first precursor present on the curved surface of the lens reacts with the first oxidizer to form a high refractive index layer of the film; exposing the high refractive index layer to a second precursor such that the second precursor is deposited on the high refractive index layer; and exposing the second precursor on the high refractive index layer to a second oxidizer such that the second precursor present on the high refractive index layer reacts with the second oxidizer to form a low refractive index layer of the film.
