ABSTRACT:
A lenticular array in silicon is made by anisotropically etching a V-shaped groove in a 100 silicon wafer wherein the walls of the V are made by intersecting 111 planes and exposing the surface having the V-grooves therein to a polishing etch whereby a series of lenses is formed between the V-grooves.
