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.
Méthode et appareil pour fabriquer un moule d'optique, le procédé de fabrication utilisant une mince plaque flexible ou pliable. On serre des prismes d'optique ensemble et on applique du métal à la surface des prismes pour former une mince couche plane de matériau pliable. On utilise ensuite un modèle de courbure sur lequel on presse la mince couche pour lui donner la configuration souhaitée. Puis on applique d'autre métal à l'endos de la mince couche jusqu'à obtention d'une épaisseur suffisante pour que le moule d'optique soit propre à recevoir un dépôt de matériau à lentille pour la production d'une lentille optique.
