Abstract
In a hybrid lens forming method for transferring an aspherical composite layer made of an ultraviolet-curing resin, which is curable by irradiation with ultraviolet rays, onto one surface of a convex lens by using a forming die, the forming die is made of a material which transmits ultraviolet rays, and the aspherical composite layer is transferred onto the convex lens by applying ultraviolet rays from the side of the forming die and curing the ultraviolet-curing resin with ultraviolet rays transmitted through the forming die.
Claims10
A hybrid lens forming method for transferring a composite layer made of a photocurable resin, which is curable by irradiation with light rays, onto at least one surface of a single lens by using a forming die, wherein said forming die is made of a material which transmits light rays, and said composite layer is transferred onto said single lens by applying the light rays from the side of said forming die and curing said photocurable resin with the light rays transmitted through said forming die.
A hybrid lens formed by transferring a composite layer made of a photocurable resin, which is curable by irradiation with light rays, onto at least one surface of a single lens by using a forming die, wherein a lens frame is formed integrally with said composite layer.
