Patent ID: 8641936

Claim:
A method for manufacturing an optical structure of curable material, comprising: molding and curing a first structure of a first curable material on a substrate; molding and curing a second structure of a second curable material on a first surface of the first structure facing away from the substrate, so that at the first surface of the first structure a boundary surface between the first structure and the second structure forms and so that the first structure is not covered by the second structure in a passage area; and introducing a solvent into the passage area after molding and curing the second structure in order to dissolve the first curable material of the first structure so that a cavity is formed between the second structure and a surface of the substrate, wherein the first curable material is soluble for the solvent after curing and the second curable material is insoluble for the solvent after curing, the method further comprising: molding and curing a fourth structure of the first curable material on the second structure; molding and curing a fifth structure of the second curable material on the fourth structure, so that the fourth structure is not covered at the passage area; and wherein introducing the solvent into the passage area is further executed after molding and curing the fifth structure in order to further dissolve the first curable material of the fourth structure, so that further a further cavity is formed between the fifth structure and the second structure which is fluidically connected to the cavity between the second structure and the substrate.
