Replication of an antireflecting element in COC plastics using a hot embossing technique

Abstract

Replication of surface relief microstructures into COC (cyclic olefin copolymers) plastics using a hot embossing technique is considered. The replication accuracy has been investigated by optical characterization and scanning electron microscopy (SEM) of the replicated surface profile, which is a diffractive anti-reflection layer. Good agreement between theoretical and experimental results is shown.
