Abstract

A system and method for extrusion replication of microstructures to make microreplicated optical films. The system includes press roll and a replicating member. The replicating member includes a low thermal diffusivity material having a microreplicated outer surface or an organic material having a microreplicated outer surface. An inorganic conformal coating is disposed over the patterned outer surface of the organic or low thermal diffusivity material.
