Abstract
A method of replicating at least one optical element is provided, the method including the steps of: providing a substrate with two large sides and at least one pre-defined replication site defined by a through hole or blind holes at corresponding locations on both large sides of the substrate; and adding, by replication, a replicated structure to the substrate, the replicated structure adhering to the substrate and having, at the replication site, replication material in the through hole or in the two blind holes, respectively and a first replicated surface and a second replicated surface, the first and second replication surfaces facing towards opposite sides.
