Zusammenfassung:Substrate (3) carries a patterned optical coating on a curved surface e.g. of a lamp (112), using a mask which shrouds at least part of the curved surface(1) of the lamp bulb (100). The coating (25) is applied by physical vapor deposition, and the mask removed leaving the uncovered zone (29) with the coating and the neighboring covered zone (29) free of coating. The substrate can be of a glass, glass ceramic, metal or plastics material.
