Abstract
A method of making an array (18) of aberrated optical elements (20). The method comprises the steps of providing a substrate having a first surface with forming elements thereon, and controlled working a localized region on the first surface of the substrate. The controlled working is of a magnitude sufficient to aberrate one or more of the forming elements in an affected site surrounding the localized region.
