Title:
PRODUCTION OF POLYGONAL ROTATABLE SCAN PLATE*AND POLYGONAL SCAN PLATE MADE BY SAME METHOD
Document Type and Number:
Japanese Patent JPS5694319
Kind Code:
A
Abstract:
A polygonal shaped, multi-faceted rotary scanner comprising a plurality of optically flat, reflective surfaces on facets (5 to 12) are integrally bonded to a multi-faceted, polygonal base (4, Figure 2) 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 accurately located in position at the precise angle by contact with an upper and a lower facet of a master multi-faceted polygonal fixture and the flat reflective surface is adhesively bonded to the corresponding facet of the polygonal base (4), said polygonal base (4) being assembled concentrically between the upper and lower facets of the fixture prior to application of a small quantity of a liquid adhesive to the surface of the facets (5 to 12) of the polygonal base, which adhesive on hardening, adhesively bonds the reflective layers of the or each master preform to the appropriate facets of the polygonal base (4).
