A system for accurately aligning a plurality of optical elements includes a wafer into which are formed a plurality of holes. The user interface displays a plurality of alphanumerical characters and, in response to user input that functions to target one of the plurality of alphanumerical characters, the user interface displays the targeted alphanumeric character with a highlighted feature that distinguishes the targeted alphanumeric character from the non-targeted alphanumeric characters. The olefin-based block copolymer of the invention can be used to prepare an adhesion promoter that provides excellent adhesion of subsequent coating layers to olefinic substrates like TPO and superior properties as compared to previously used adhesion promoters containing chlorinated polyolefins.
