Abstract: Provided is a method of coating a substrate is provided. The method includes providing at least one test substrate, b) a programmed physical thickness (T) for at least one layer of the multi-layered coating, and c) a design file including a target physical thickness and target spectral performance for the at least one layer of the multi-layered coating; depositing the at least one layer onto the test substrate to form an applied layer having an optical thickness; measuring a spectral performance of the applied layer; and comparing the programmed physical thickness (T) to the optical thickness of the applied layer, thereby generating a data set (ΔT). A system and an optical article produced by the method are also disclosed.

Abstract: A pre-fabricated assemblies and methods of use for coating substrates are described. The pre-fabricated assembly includes at least two layers in a stack, each layer includes at least one raw material. The raw material in each layer may be a dielectric material. One type of stack has one outer layer as an exposed layer. One type of stack has an exposed portion with each layer, and a portion of all layers is exposed. In use, a stack in a pre-fabricated assembly is positioned in a vacuum chamber system and energy is delivered sequentially to the exposed layer, removing at least a portion of each exposed layer. Each layer becomes an exposed layer and is deposited on the substrate in a sequential manner. The pre-assembled raw material stack is used to fabricate a multi-layered coating, such as a multi-layered coating for an optical or ophthalmic article.
