Patent ID: 8440256

Claim:
A method of forming an anti-reflective coating on a glass substrate using combustion deposition, the method comprising: providing a glass substrate having at least one surface to be coated; selecting a reagent, the reagent being selected such that at least a portion of the reagent is used in forming the coating; introducing a precursor to be combusted with the reagent; combusting, using at least one infrared burner, at least a portion of the reagent and the precursor to form a combusted material, the combusted material comprising non-vaporized material; providing the glass substrate at a distance of about 2-5 mm from the at least one IR burner and in an area so that the glass substrate is heated sufficiently to allow the combusted material to form the anti-reflective coating, directly or indirectly, on the glass substrate; and providing a linear estimate of substrate temperature rate of rise of only about 16.5° C./burner/m/min.
