Title (EN) LENS, LENS UNIT, AND LENS MANUFACTURING METHOD
(FR) LENTILLE, UNITÉ DE LENTILLE ET PROCÉDÉ DE FABRICATION DE LENTILLE
(JA) レンズ、レンズユニット及びレンズの製造方法
Abstract: front page image
(EN) This invention provides a lens, a lens unit, and a lens manufacturing method that reduce strain in the lens while decreasing the number of components and the amount of labor required for assembly and also effectively reduce unneeded light, which can cause ghosting and the like. Slits are formed in a light-blocking film formed on the lens, so even if said light-blocking film contracts, the slits divide up the resulting compressive stress, reducing strain in the lens as much as possible.
(FR) Cette invention concerne une lentille, une unité de lentille et un procédé de fabrication de lentille qui permet de réduire la déformation dans la lentille tout en réduisant le nombre de composants et la quantité de travail requise pour l'assemblage, et également qui réduit efficacement la lumière inutile, ce qui peut générer un effet fantôme et analogue. Des fentes sont formées dans un film bloquant la lumière formé sur la lentille ; ainsi, même si le film bloquant la lumière se contracte, les fentes divisent la contrainte de compression résultante, ce qui réduit autant que possible la déformation dans la lentille.
(JA)  部品点数・組立工数削減を図りつつ、レンズの歪みを抑制し、更にはゴースト等を招く不要光を有効に抑制できるレンズ、レンズユニット及びレンズの製造方法を提供する。レンズに形成された遮光膜にはスリットが形成されているので、遮光膜が収縮した場合でも、スリットにより圧縮応力が分断されるため、レンズの歪みを極力抑制できる。
