Abstract:
(EN) An optical element capable of suppressing reduction in light resistance and bleed-out of light stabilizers caused from exposure to 380 nm to 420 nm laser light.  The optical element is used in an optical pick-up device employing a light source firing a 380 nm to 420 nm laser light beam, and is provided with a shaped part (50) comprised of alicyclic olefin resin, and a light stabilizer layer (55) formed on the surface of the shaped part (50).
(FR) L'invention concerne un élément optique capable d'éviter la réduction de la résistance à la lumière et l'exsudation d'agents de stabilité à la lumière provoquée par une exposition à une lumière laser de 380 nm à 420 nm. L'élément optique est utilisé dans un dispositif de lecture optique utilisant une source de lumière émettant un faisceau de lumière laser de 380 nm à 420 nm, et est muni d'une pièce façonnée (50) constituée d'une résine d'oléfine alicyclique, et d'une couche d'agent de stabilité à la lumière (55) formée sur la surface de la pièce façonnée (50).
(JA)  本発明は、光学素子において、380nm~420nmのレーザ光の被照射による耐光性の低下及び耐光安定剤のブリードアウトを抑制する。本発明の光学素子は、波長が380nm~420nmのレーザ光を射出する光源を用いた光ピックアップ装置に用いられる光学素子であって、脂環式オレフィン樹脂から構成された成形部50と、成形部50の表面に形成された耐光安定剤層55と、を備えることを特徴とする。
