Title (EN) METHOD OF MANUFACTURING RESIN LENS, MOLD FOR MANUFACTURING RESIN LENS, AND FILM FOR RESIN LENS INSERTION
(FR) PROCÉDÉ DE FABRICATION D'UNE LENTILLE EN RÉSINE, MOULE POUR LA FABRICATION D'UNE LENTILLE EN RÉSINE ET FILM POUR L'INSERTION D'UNE LENTILLE EN RÉSINE
(JA) 樹脂レンズの製造方法、樹脂レンズ製造用モールド、及び樹脂レンズ内挿用フィルム
Abstract:
(EN) In a method of manufacturing a resin lens, a resin film (3) is provided between molds (10, 14), gaps (15, 16) are formed between the resin film (3) and the molds (10, 14), and the sides of the gaps (15, 16) are covered by covering the side surfaces of the molds (10, 14) and the side surface of the resin film (3) with a covering material (17) to form the gaps (15, 16) into a substantially closed space having a filling opening.  A lens material is poured into the substantially closed space from the filling opening until the space is full and the lens material is polymerized and hardened to form a resin lens consisting of the hardened resin and the resin film which are integrated together.  A projection (11) for maintaining the gap (15) at a predetermined width is provided to the outer periphery of the inner surface of the mold (10).
(FR) L'invention porte sur un procédé de fabrication d'une lentille en résine, dans lequel un film de résine (3) est disposé entre des moules (10, 14), des espaces (15, 16) sont formés entre le film de résine (3) et les moules (10, 14) et les côtés des espaces (15, 16) sont recouverts par un recouvrement des surfaces latérales des moules (10, 14) et de la surface latérale du film de résine (3) avec une matière de recouvrement (17) pour mettre les espaces (15, 16) sous forme d'un espace pratiquement fermé ayant une ouverture de remplissage. Une matière de lentille est versée dans l'espace pratiquement fermé à partir de l'ouverture de remplissage jusqu'à ce que l'espace soit plein et la matière de lentille est polymérisée et durcie pour former une lentille en résine constituée de la résine durcie et du film de résine qui sont intégrés ensemble. Une partie saillante (11) pour le maintien de l'espace (15) à une largeur prédéfinie est pourvue sur la périphérie externe de la surface interne du moule (10).
(JA)  本発明の樹脂レンズの製造方法において、モールド(10、14)間に樹脂フィルム(3)を配し、モールド(10、14)と樹脂フィルム(3)との間に間隙部(15、16)を形成するとともに、モールド(10、14)の側面と樹脂フィルム(3)の側面とを被覆材(17)で覆うことによって間隙部(15、16)の側方を覆い、間隙部(15、16)を、充填口を有する略閉塞空間にする。充填口から略閉塞空間にレンズ材料を注入充填し、レンズ材料を重合硬化させ、硬化した樹脂と樹脂フィルムとが一体化してなる樹脂レンズを形成する。モールド(10)として、モールド(10)の内面の外周部に、間隙部(15)を所定の幅に保持するための突出部(11)が設けられたものを用いる。
