Abstract
In a method for manufacturing a structure of curable material, a first structure from a first curable material is molded and cured on a substrate, and a second structure of a second curable material is molded and cured 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 forms between the first and second structures so that the first structure is not covered by the second structure in a passage area. A solvent is introduced into the passage area to dissolve the first curable material of the first structure so that a cavity forms between the second structure and the first surface of the substrate. After curing, the first curable material is soluble and the second curable material is insoluble for the solvent. An optical component and an optical layer stack are made of curable material.
