(JA) レンズ、レンズユニットおよび撮像装置
Abstract:
(EN) A lens according to an embodiment of the present invention is provided with: a lens body; a dielectric multilayer film provided on the surface of the lens body; and a liquid-repelling film provided on the dielectric multilayer film. The arithmetic average roughness Ra at the surface of the liquid-repelling film is no greater than 2 nm.
(FR) Selon un mode de réalisation, la présente invention concerne une lentille comprenant : un corps de lentille ; un film multicouche diélectrique disposé sur la surface du corps de lentille ; et un film déperlant disposé sur le film multicouche diélectrique. La rugosité moyenne arithmétique Ra à la surface du film déperlant est inférieure ou égale à 2 nm.
(JA) 本発明の一態様に係るレンズは、レンズ本体と、レンズ本体の表面に設けられる誘電体多層膜と、誘電体多層膜上に設けられる撥液膜と、を備える。撥液膜の表面における算術平均粗さRaは、2nm以下である。
