Abstract:
(EN) A lens according to one embodiment of the present invention is provided with: a lens main body that contains a polymer material; and an inorganic film that is formed on the surface of the lens main body. The polymer material has a water absorption rate of more than 0% by mass but 0.05% by mass or less. The inorganic film has a Vickers hardness of 600 HV or more.
(FR) Selon un mode de réalisation, la présente invention concerne une lentille pourvu : d'un corps principal de lentille qui comprend un matériau polymère; et d'un film inorganique formé sur la surface du corps principal de lentille. Le matériau polymère présente un taux d'absorption d'eau supérieur à 0% en masse mais inférieur ou égal à 0,05% en masse. Le film inorganique présente une dureté Vickers supérieure ou égale à 600 HV.
(JA) 本発明の一態様に係るレンズは、高分子材料を含むレンズ本体と、レンズ本体の表面に形成された無機膜と、を備える。高分子材料は、吸水率が0質量%より高く0.05質量%以下である。無機膜は、ビッカース硬度が600HV以上である。
