An electrophoresis plate has a plurality of separation channels provided inside a substrate. The approach includes steps of treating surface of a base film, forming a tie layer on the base film, forming a metal conductive layer on the tie layer, and depositing a metal on the metal conductive layer by radiating electronic beams to form a metal plated layer thereon. Providing at least one acentric, graded, reflective coating allows designing projection lenses that allow highly uniform field illumination, combined with high total transmittance. Example actions to be performed include searching for information, storing information, posting information, sending information, enhancing information, and so on.
