A second lens (20) has a third mark (22) on a first surface (21) thereof. The first lens (10) is disposed on the second lens (20) with the second surface (13) and the first surface (21) facing each other, and the position of the second mark (14) and the position of the third mark (22) are matched with each other by translating the first lens (10). In this state, the tilt of the first lens (10) is changed to match the position of the first mark (12) and the position of the third mark (22).
Disclosed is an optical element wherein a fine shape etc. is transferred precisely to the outer edge side of a lens while increase in cycle time is prevented. In the optical element, the outermost periphery of the fine shape (FS) is covered, from the outside in the direction perpendicular to the optical axis (OA), with a protrusion section (14) provided at a flange part (12). Accordingly, in injection molding, with the resin introduced into the molding cavity (CV) formed in the mold, the molding cavity section corresponding to the resin inflow port side of the protrusion section (14) provided at the flange part (12) is filled first, and thereafter the molding cavity section corresponding to the fine shape (FS) adjacent to the protrusion section (14) is filled. Preheating a mold surface section (S11), for transferring the fine shape (FS), of a movable mold (41) with the resin accumulated in the molding cavity corresponding to the protrusion section (14) suppresses the temperature reduction of the mold surface section (S11) corresponding to the fine shape (FS).
Provided is a mold aligning apparatus for making the center axes of a pair of molds coincide precisely with each other. A position-determining sensor (70) is installed on a movable mold (41). Thereby the position of the movable mold (41) relative to the fixed mold (42) can be measured precisely, even when positional deviation occurs between the movable mold (41) and a mold-mounting plate (44) supporting the movable mold (41). Further, in the operation of closing the movable mold (41) with the fixed mold (42), the mold-aligning plate (51) is controlled so as to bring the output of the position-measuring sensor (70) to a prescribed level regarding the three axis directions of X-direction, Y-direction, and θ-direction, making the center axes of the movable mold (41) and the fixed mold (42) coincide precisely in mold clamping. Thereby, the reproducibility of properties of the molded products are improved.
Provided is a molding die for molding an optical element. A molding die (100) comprises: a base material (1); a heat-insulating layer (2) formed by means of thermal spraying onto the surface of the base material (1); a first plating layer (3) which contains Ni and P formed on the surface of the heat-insulating layer (2), and which is finished to the desired surface roughness; and a second plating layer (4) which contains Ni, P, and Cu formed on the surface of the first plating layer (3), and which has a molding face (4a) micromachined to correspond to the optical surface shape of an optical element.
