(FR) LENTILLE REVÊTUE, UNITÉ DE LENTILLE ET MODULE DE CAMÉRA
(JA) 膜付きレンズ、レンズユニットおよびカメラモジュール
Abstract
(EN)
Provided is a coated lens, lens unit, and camera module capable of forestalling reduced visibility due to lens haze and accumulation of water droplets on the lens surface, thereby keeping transmittance high. This coated lens 13 is provided at the object-facing end of a barrel 12 and has an object-facing lens obverse surface 13a and a focal-plane-facing lens reverse surface 13b. The lens obverse surface 13a and lens reverse surface 13b have formed thereon an antiglare coating 30. The lens reverse surface 13b has a hydrophilic coating 31 with a thickness of at most 50 nm formed over the antiglare coating 30.
(FR)
L'invention concerne une lentille revêtue, une unité de lentille et un module de caméra susceptibles d'éviter une visibilité réduite due à une diffusion globale de la lentille et à l'accumulation de gouttelettes d'eau sur la surface de la lentille, permettant ainsi de maintenir une transmittance élevée. Ladite lentille revêtue (13) est disposée au niveau de l'extrémité faisant face à l'objet d'un charnon (12) et comporte une surface d'avers de lentille (13a) faisant face à l'objet et une surface d'envers de lentille (13b) faisant face au plan focal. La surface d'avers de lentille (13a) et la surface d'envers de lentille (13b) comportent un revêtement antireflet (30). La surface d'envers de lentille (13b) comporte un revêtement hydrophile (31) d'une épaisseur de 50 nm au maximum, formé sur le revêtement antireflet (30).
