摘要： PROBLEM TO BE SOLVED: To improve the formation precision of a lens part when a lens array is manufactured by pressing a molding die.
SOLUTION: A lens connection member 4 is mounted on a transfer surface of the molding die 1 and materials to be molded 7 are arranged at lens arrangement parts 5 provided to the lens connection member 4. The materials to be molded 7 are light-transmissive materials and softened by heating or the like. While sandwiched between the transfer surface of the molding die 1 and a transfer surface of a molding die 1' and pressed together with the lens connection member 4, the softened materials to be molded 7 are hardened to form lenses, which are joined with the lens connection member 4 to form a lens array. During the pressing, the materials to be molded are deterred from flowing to outside the transfer surface 2 of the molding die 1 with frictional force generated between a resistance part 6 and the materials to be molded , so force of the flow to a formation part of the lens correspondingly increases, so that transfer of a portion of the lens becomes excellent.

摘要： PROBLEM TO BE SOLVED: To improve the preciseness of lens array forming when the lens array is manufactured by pressing forming molds.
SOLUTION: A lens connecting part 4 is placed on the transfer mold 1 and a material to be formed 7 is placed at each lens placing part 5.

摘要： PROBLEM TO BE SOLVED: To provide a numerical analysis method where the forming process of a glass optical element, especially its pressing step, can be estimated in good precision.
SOLUTION: A glass raw material is divided to a limited number of micro-areas and the processing time of forming is divided to a plurality of time steps Δt for the numerical calculation of a forming process where the glass optical element is formed by pressing the glass raw material softened with heat in a forming die and then the glass optical element is formed after cooling. When thermal stress analysis associated with heat transfer analysis and stress deformation analysis is performed, the thermal stress analysis (S104, S105) is performed for an analysis model (S107) under the condition that the time steps Δt are satisfied with the formula of Δtc=(ρC/6κ)×ΔL
2 or more (wherein, ρ is a density, C is specific heat, κ is thermal conductivity and ΔL is an element dimension around the contact part of the glass raw material with the forming die).

A lens lower surface mold 28-1 and a lens upper surface mold 29-1 having an effective diameter smaller than the diameter m of the hole 27 are respectively formed on the lower pressing mold 28 and an upper pressing mold 29. The lens is molded with pressing load nearly equal to the pressure for pressing the material 25 by the upper and lower molds. By using different material for the materials 25 and the member 26, respectively, the optical noise of the lens is restrained. By using metal for the member 26, soldering is facilitated in the case of assembling the lens in the device body.
