Abstract: A flow lens element is obtained by integrally molding a resin layer on a glass member. A relief portion for preventing the resin material from adhering to an outer circumferential portion of the glass member is provided between the circumferential portion and an optical portion of the glass member.

Abstract: A method and apparatus for molding optical elements in which a resin layer is accurately formed on a surface of a desired shape without the occurrence of peeling between a glass member and a resin layer and between a mold member and the resin layer when the resin layer is molded. This is accomplished by a first step of placing the glass member upon a supporting member, a second step of holding the glass member in a state in which the surface thereof is spaced away from the molding surface of the mold member by a predetermined distance, and a third step of moving the mold member and the supporting member relative to each other, after the resin material, which has been charged into a space defined by the molding surface and the surface of the glass member, has cured to a predetermined ratio of polymerization, in such a manner that glass member is supported on the resin layer independently.

Abstract: A method and apparatus for molding optical elements in which peeling between a glass member and a resin layer and between a mold member and the resin layer will not occur while at the same time it is possible to accurately bring the central axis of the glass member and the central axis of the molding surface into alignment. This is accomplished by a first step of placing the glass member upon a support portion, a second step of positioning the glass member relative to the mold means when a resin material, which has been charged into a space defined by the molding surface and the surface of the glass member, exhibits a viscosity within a predetermined range, a third step of holding the glass member at a predetermined position until the resin material cures to a predetermined ratio of polymerization, and a fourth step of releasing the glass member from the held state after the resin material has cured to the predetermined ratio of polymerization.

Abstract: A plurality of mold members are disposed on an index table to be intermittently rotatably driven. Energy sources for curing the activation energy curable resin at positions to which the mold members are intermittently moved, a first robot for supplying a molding parent material to the mold member, a second robot for taking out an optical element after molding from the mold member, and a third robot for supplying the activation energy curable resin before supplying the molding parent material to the mold member are disposed proximate to the index table. The operations of each robot are performed together at each moved position of the mold member.

Abstract: A method of molding an optical element in which a required amount of a resin material can be accurately supplied without air bubbles becoming entrapped in the resin material when it is supplied. The method includes a first step of making a tip of resin material supply means approach a molding surface until the tip is a predetermined distance away from the molding surface, a second step of discharging a predetermined amount of the resin material from the tip of the supply means while the tip of the supply means is the predetermined distance away from the molding surface, and a third step of discharging the resin material from the tip at a predetermined discharge rate, until a required amount of the resin has been supplied, while the tip of the supply means is moved in a direction away from the molding surface as the lower end of the resin material discharged from the tip is maintained in contact with the molding surface.
