Abstract
Provided are: an optical communication lens which exhibits improved formability, is capable of suppressing contamination and the like during the production step, and reduces costs; an optical communication module using the same; and a molding die. After the material cools, a movable mold (MM) is displaced so as to integrally move away from a fixed mold (FM). During this displacement, the contact surface (FM3) of the fixed mold (FM) is positioned at delta2=L/10 to L/2 in the optical axis direction from the innermost point of the fixed mold (FM); hence, the molded product is stuck to the movable-mold (MM) side. Also, even if for example a burr is formed along the parting line, there is little risk that the broken burr would adhere to the optical surface of the lens. Furthermore, the contact surface (FM3) of the fixed mold (FM) is positioned at delta2=L/10 to L/2 in the optical axis direction from the innermost point of the fixed mold (FM); hence, it is possible to separate the gate (GT) from the optical surface (S2), and when cutting the gate and performing the polishing treatment, the adhesion of plastic bits and polished material to the optical surface (S2) is suppressed.
