ABSTRACT:
A polygonally shaped, multifaceted rotary scanner comprising a plurality of optically flat, reflective surfaces on the facets. The reflective surfaces are integrally bonded to a multifaceted, polygonal base at precise angles to the axis of rotation by a replication technique in which each optically flat reflective surface is produced on the surface of a flat master preform, and the flat master preform is then accurately located in position at the precise angle relative to the base by contact with upper and lower facets of a master multifaceted polygonal fixture. The flat reflective surface is then adhesively bonded to the corresponding facet of the polygonal base (while the polygonal base is arranged concentrically between the upper and lower facets of the fixture) by the application of a small quantity of a liquid adhesive to the surface of the facet of the polygonal base. On hardening, the adhesive bonds the reflective layer of each master preform to the appropriate facet of the polygonal base.
