ABSTRACT:
An optical element of polymeric material is provided with a microstructured surface, thereby rendering the surface substantially non-reflecting while maintaining a high degree of transmissivity. The element is formed via replication from a stamper prepared from a glass original having a similar microstructured surface which is formed by etching a cleaned surface of the glass in vapors of hydrofluoric acid followed by sputter etching with inert gas ions.
