Abstract
A method for making lightweight mirrors. The method consists of metallizing a precise pattern onto the back surface of a mirror element so as to provide a surface to which stiffening ribs or other components, such as flexure components, may readily be soldered. The method according to the present invention avoids the expense of conventional machining techniques and provides a better quality bond than is attainable by normal cementing. It also eliminates the risk of distortion and spoilage that is borne in fusing by firing to the softening point of the glass.
