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 mould with a liquid light-transmissive polymeric material, b) curing the polymeric material to obtain a replica layer, c) removing the mould. 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 moulds, 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.

Abstract: The invention relates to a module provided with a thin-film circuit which comprises an integrated trimmable capacitor. At least one electrically conducting layer (2, 4) of the capacitor has a structured surface with recesses. This finger-type design has the result that the actual capacitor is composed of several capacitors connected in parallel. After the total capacitance value has been determined, this total capacitance value can be fine tuned through a selective cutting-off of fingers, i.e. of capacitors, from the main surface of the electrically conducting layer (2, 4).
