Abstract
(EN) A camera optical lens (10), the camera optical lens (10) comprising in total seven lenses, the seven lenses being, in order from object side to image side: a first lens (L1) having a positive refractive power, a second lens (L2), a third lens (L3) having a positive refractive power, a fourth lens (L4) having a negative refractive power, a fifth lens (L5), a sixth lens (L6) having a positive refractive power, and a seventh lens (L7) having a negative refractive power. At least one from among the first lens (L1) to the seventh lens (L7) contains a free-form surface, and the camera optical lens (10) has good optical properties, while also satisfying ultra-thin and wide-angle design requirements.
(FR) L'invention concerne une lentille optique de caméra (10), la lentille optique de caméra (10) comprenant sept lentilles au total, les sept lentilles étant, dans l'ordre du côté objet au côté image : une première lentille (L1) ayant une puissance optique positive, une deuxième lentille (L2), une troisième lentille (L3) ayant une puissance optique positive, une quatrième lentille (L4) ayant une puissance optique négative, une cinquième lentille (L5), une sixième lentille (L6) ayant une puissance optique positive et une septième lentille (L7) ayant une puissance optique négative. Au moins lentille une parmi la première lentille (L1) à la septième lentille (L7) contient une surface de forme libre, et la lentille optique de caméra (10) a de bonnes propriétés optiques, tout en satisfaisant également des exigences de conception ultra-minces et à grand angle.
(ZH) 一种摄像光学镜头(10),摄像光学镜头(10)共包括七片透镜,七片透镜自物侧至像侧依序为:具有负屈折力的第一透镜(L1),第二透镜(L2),具有正屈折力的第三透镜(L3),具有负屈折力的第四透镜(L4),第五透镜(L5),具有正屈折力的第六透镜(L6),以及具有负屈折力的第七透镜(L7);第一透镜(L1)至第七透镜(L7)中的至少一个含自由曲面,摄像光学镜头(10)具有良好光学性能的同时,满足超薄化、广角化的设计要求。
