Mirror with optically polished surface

A method is disclosed for reproducing a duplicate having a mirror optical surface from a master optical surface. In particular, a master is produced by conventional methods such as deposition and grinding to provide an optical surface. Next, a nonadhering layer of a reflective material is applied to...

Zusammenfassung:	A method is disclosed for reproducing a duplicate having a mirror optical surface from a master optical surface. In particular, a master is produced by conventional methods such as deposition and grinding to provide an optical surface. Next, a nonadhering layer of a reflective material is applied to the optical surface of the master, which may be used repeatedly. An adhesive is applied over the nonadhering layer and a suitable base structure is pressed into the adhesive. When the adhesive has been cured, the base, and adhesive and nonadhering layers are removed. The resulting surface of the nonadhering layer is a precise replica of the optical surface of the master.
