this citation summarizes a one-page announcement of technology available for utilization. a technique has been proposed to form precise mirror surfaces on lightweight, rigid, imprecise graphite-composite substrates. the technique should enable the fabrication of lightweight mirrors of high surface finish suitable for use at short wavelengths. heretofore, the irreducible small-scale roughness of the surfaces due to the structures of composite materials inhibited the use of composite mirrors at short wavelengths. the technique resembles that used to make lightweight replica mirrors and gratings. a layer of parting material is deposited on a master optical surface of the precise desired shape this parting layer must be very thin to minimize degradation of the replica
