Title (EN) OPTICAL GLASS
(FR) VERRE OPTIQUE
(JA) 光学ガラス
Abstract:
(EN) An optical glass is provided which is suitable as an imaging lens used in a vehicle-mounted camera exposed to harsh environments, and has a high refractive index and high strength. This optical glass has a reinforcement layer in the surface layer, wherein the depth of the reinforcement layer is 1μm or more from the surface of the optical glass, and the refractive index (nd) of the optical glass is 1.73-2.10.
(FR) La présente invention concerne un verre optique qui est approprié comme lentille d'imagerie utilisée dans une caméra montée sur véhicule exposée à des environnements hostiles, et qui a a un indice de réfraction élevé et une résistance élevée. Ce verre optique présente une couche de renforcement dans la couche de surface, la profondeur de la couche de renforcement étant de 1 µm ou plus à partir de la surface du verre optique, et l'indice de réfraction (nd) du verre optique étant de 1,73 à 2,10.
(JA) 過酷な環境に曝される車載用カメラに用いられる撮像レンズ等に好適な、屈折率が高くかつ強度が高い光学ガラスを提供する。表層部に強化層を有する光学ガラスであって、前記強化層の深さは前記光学ガラスの表面から1μm以上であり、前記光学ガラスの屈折率(nd)は1.73~2.10である光学ガラス。
