Abstract
The invention concerns a process of manufacturing optical components. A replication tool, a sub-master or a replica is manufactured using a structured element (for example a master) and a substrate. A structure of the structured element is replicated into liquid or plastically deformable material disposed at a first place on said substrate, then hardened to make it dimensionally stable, whereon the structured element is removed. These replicating, hardening and removing steps are repeated for a second, third, etc. place on said substrate the same structured element.
