Abstract

Method and apparatus is disclosed for manufacturing a reflex mold wherein a flexible or bendable, thin plate is provided for use in the manufacturing process. A reflex prism assembly is clamped together and metal is applied over the surface of the prisms to make a flat, thin layer of bendable material. A model of curvature is then provided and the thin layer is clamped on the model to assume the desired configuration. More metal is then applied over the back surface of the thin layer until sufficient thickness is obtained to make the reflex mold suitable to receive deposition of lens material for the production of a reflex lens.
