Abstract
A surface relief structure consisting of a random distribution of surface features with varying feature profile and depth, is described. The texture serves to suppress the reflection of electromagnetic waves in the optical region of the spectrum without dispersing any portion of the spectrum by diffraction. Processes for fabricating the random distribution anti-reflecting textures in common materials are also described. The disclosed textures are particularly useful as anti-reflecting covers for displays, and as directly molded anti-reflecting surfaces in eyeglass lenses. Other applications such as covers for artwork, and improved solar cells are made practical by the invention.
