1. In the method of providing a myriad of irregularly outlined surfaces carried by a support to form a mold, certain of said surfaces dimensionally offset from one another in a common longitudinal direction generally parallel to incident radiation to be reflected, said surfaces corresponding to radiation reflecting surfaces each oriented in such a way that as a group that collectively reflect radiation essentially as if they were a continuous reflecting surface, the steps that include:

  • (a) cutting irregularly outlined segments of a body to form said irregularly outlined surfaces, facing in said longitudinal direction, and to form spaces between the segments,(b) longitudinally translating said segments in said common longitudinal direction relatively toward a conforming surface while blocking lateral displacement of said segments, thereby maintaining said spaces and bringing said segments into a position wherein the segment surfaces touch said conforming surface,(c) and thereafter fixing said segments in said position to form the mold.
