Patent ID: 7473331

Claim:
A method for applying an optical coating to an article surface of an article, comprising the steps of: providing a polyimide film as a deposition substrate; thereafter applying an aluminum layer as a first release system to the deposition substrate; thereafter depositing the optical coating as a multi-layer coating onto the deposition substrate, with the first release system between the optical coating and the deposition substrate, wherein the optical coating has a first face contacting the first release system, and a second face remote from the first face; thereafter applying a second release system and a transfer substrate to the second face of the optical coating, wherein the first release system is dissolvable in a first-release-coating solvent that does not dissolve the second release system, the first-release-coating solvent comprising water, hydrochloric acid and copper sulfate; thereafter dissolving the first release system in the first-release-coating solvent to separate the optical coating from the deposition substrate, wherein the first face of the optical coating becomes an exposed free face; thereafter furnishing the article having the article surface; thereafter affixing the first face of the optical coating to the article surface; and thereafter separating the transfer substrate from the second face of the optical coating, wherein the optical coating includes alternating layers of Si and SiO, or alternating layers of SiO 2 and Ta 2 O 5 .
