Abstract
The invention relates to a method and an apparatus for manufacturing an optical device by means of a replication method comprising the steps of: a) filling a gap between a substrate and a mold with a liquid light-transmissive polymeric material, b) curing the polymeric material to obtain a replica layer, c) removing the mold. In order to manufacture optical devices, such as lenses having a larger NA-value, it is proposed according to the present invention that the replication method is repeated at least two times while using the same or different molds, and that the substrate, together with one or more replica layers obtained during one or more previous runs of the replication method, is used as a substrate for the next run of the replication method.
