Title
(EN) LENS UNIT AND CAMERA MODULE
(FR) UNITÉ DE LENTILLE ET MODULE DE CAMÉRA
(JA) レンズユニットおよびカメラモジュール
Abstract
(EN) The present invention provides a lens unit and a camera module, the lens unit being capable of preventing fogging of a back surface of a first lens and preventing deterioration of optical performance by reliably waterproofing a lens space between the first lens and a second lens without using an O-ring. Since a first lens 13 located closest to the object side and a second lens 14 adjacent to the first lens 13 on the image side among a plurality of lenses are bonded and waterproofed by a low moisture permeable adhesive ad, a space between the first lens and a lens tube is reliably waterproofed without using an O-ring, thereby making it possible to prevent fogging of a back surface of the first lens and prevent deterioration of optical performance.
(FR) La présente invention concerne une unité de lentille et un module de caméra, l'unité de lentille étant capable d'empêcher la formation de buée sur une surface arrière d'une première lentille et d'empêcher la détérioration de performance optique par l'imperméabilisation fiable d'un espace de lentille entre la première lentille et une seconde lentille sans utiliser un joint torique. Étant donné qu'une première lentille 13 située le plus près du côté objet et une seconde lentille 14 adjacente à la première lentille 13 sur le côté image parmi une pluralité de lentilles sont liées et imperméables à l'eau par une adhésive perméable à faible humidité, un espace entre la première lentille et un tube de lentille est rendu étanche à l'eau de manière fiable sans utiliser un joint torique, ce qui permet d'empêcher la formation de buée sur une surface arrière de la première lentille et d'empêcher la détérioration des performances optiques.
(JA) Оリングを使用することなく、第1レンズと第2レンズとの間のレンズ空間を確実に防水して第1レンズの裏面の曇りを防止できるととともに光学性能の悪化を防止できるレンズユニットおよびカメラモジュールを提供する。 複数のレンズのうち、最も物体側に位置する第1レンズ13と、この第1レンズ13に像側で隣接する第2レンズ14とが低透湿性接着剤adによって接着防水されているので、第1レンズと鏡筒との間を、Оリングを使用することなく、確実に防水して第1レンズの裏面の曇りを防止できるととともに光学性能の悪化を防止できる。
