Abstract

See full text

The invention relates to methods for fabricating antireflective surface structures (ARSS) on an optical element using a seed layer of material deposited on the surface of the optical element. The seed layer is removed during or after the etching, and serves to control etching time as well as the transmission region of the optical element having ARSS. Optical elements having ARSS on at least one surface are also provided.
