Elimination of internal reflections and diffractions from junctures in, and at the periphery of, a segmented mirror
First Claim
1. In a molded segmented mirror having individual sectors and comprising a myriad of reflecting surfaces on the front side of a molding closest to the viewer, said surfaces oriented to produce, in the eyes of the viewer, one virtual image, or separate virtual images from separate portions of such molded mirror, there being a network of zones separating the individual mirror sectors, and the sectors being metallized, the improvement comprising:
- (a) the metalizing material being applied to the sectors and not to the intervening zones,(b) the thickness of metalizing material being feathered to a partial mono-molecular thickness around the periphery of each sector.

Abstract
In a transparent molded segmented mirror having individual sectors on a transparent molding and comprising a myriad of reflecting surfaces at the rear side of the mirror away from the viewer, said surfaces located to produce, in the eyes of the viewer, a virtual image, or separate virtual images from separate portions of such molded mirror, there being zones separating the reflecting surfaces, the improvement comprising:
(a) a material coating said zones and which includes a light absorber,
(b) such material having approximately, the same index of refraction as the transparent molding,
(c) whereby undesirable reflections from said zone are substantially reduced, because light impinging thereon cannot be reflected, but is only absorbed.
Also, the thickness of light reflecting metallizing material defining the reflective surfaces may be thinned adjacent said zones, and the light absorptive coating may be applied over the thinned metallizing material; and the edges of the molding and of a glass backer may be coated with light absorptives material.
