Title
(EN) GLASS-PLASTIC HYBRID LENS
(FR) LENTILLE HYBRIDE VERRE-PLASTIQUE
(ZH) 玻塑混合镜头
Abstract
(EN) A glass-plastic hybrid lens, comprising: a glass lens (110) and at least one plastic lens (120, 130) sequentially arranged from an object side to an image side; and an ultraviolet cut-off layer (112) provided at one side of the plastic lens (120, 130) distant from the image side, the ultraviolet cut-off layer (112) and the plastic lens (120, 130) being arranged at intervals. The glass-plastic hybrid lens is simple in structure and easy to implement, the ultraviolet cut-off layer can effectively absorb or reflect the ultraviolet light irradiated to the lens and can effectively block irradiation of the ultraviolet light on the plastic lens behind, and the problem that the plastic lens is demoulded and turns yellow under irradiation of strong UV light is effectively solved, so that UV tolerance and solar irradiation tolerance of the lens are improved; moreover, a combination of a glass lens and a plastic lens is used for the lens, so that a thermal difference can be eliminated, and costs are relatively low.
(FR) L'invention concerne une lentille hybride verre-plastique, comprenant : une lentille en verre (110) et au moins une lentille en plastique (120, 130) disposées séquentiellement d'un côté objet à un côté image ; et une couche de coupure des ultraviolets (112) disposée sur un côté de la lentille en plastique (120, 130) à distance du côté image, la couche de coupure des ultraviolets (112) et la lentille en plastique (120, 130) étant disposées à des intervalles donnés. La lentille hybride verre-plastique est de structure simple et facile à mettre en œuvre, la couche de coupure des ultraviolets peut absorber ou réfléchir efficacement la lumière ultraviolette irradiée sur la lentille et peut bloquer efficacement l'irradiation de la lumière ultraviolette sur la lentille en plastique qui se trouve derrière, et le problème selon lequel la lentille en plastique est déformée et devient jaune sous l'irradiation d'une forte lumière UV est résolu efficacement, de sorte que la tolérance aux UV et la tolérance au rayonnement solaire de la lentille sont améliorées. De plus, une combinaison d'une lentille en verre et d'une lentille en plastique est utilisée pour la lentille, de sorte qu'une différence thermique peut être éliminée et les coûts sont relativement faibles.
(ZH) 一种玻塑混合镜头,包括:从物侧到像侧依次设置的玻璃镜片(110)、至少一个塑胶镜片(120,130);紫外截止层(112)设置在塑胶镜片(120,130)远离像侧的一侧,且紫外截止层(112)与塑胶镜片(120,130)间隔设置。该玻塑混合镜头结构简单,易于实现,紫外截止层可以有效吸收或者反射照射到镜头的紫外光,能够有效阻隔紫外光线对后面塑胶镜片的照射,有效解决了塑料透镜在强UV的照射下出现脱膜和变黄的问题,从而提高镜头的UV耐受性和太阳辐照耐受性,并且镜头采用玻璃镜片和塑胶镜片混合,可以有效消除热差,成本较低。
