Abstract:
1. A method of making an optics element, comprising depositing a first metallic layer on a polished replicating surface to be imparted to the optics element, depositing a backing layer comprising metallic coated porous or hollow particles on the first metallic layer deposited on the replicating surface in a manner that the backing layer particles are adhered on the first metallic layer by a metallic bond without the particles being substantially crushed or densified, depositing a cover layer on the backing layer deposited on the first metallic layer in a manner that the cover layer adheres on the backing layer, whereby the first metallic layer, the backing layer, and the cover layer form a composite lamination residing on the replicating surface, and removing the composite lamination as the optics element from the replicating surface wherein the polished replicating surface is imparted to a surface of the first metallic layer.
