(ZH) 摄像光学镜头
Abstract
(EN) An image pickup optical camera (10). From an object side to an image side, the image pickup optical camera (10) sequentially comprises seven lenses, i.e., a first lens (L1), a second lens (L2), a third lens (L3), a fourth lens (L4), a fifth lens (L5), a sixth lens (L6), and a seventh lens (L7); at least one of the first lens (L1) to the seventh lens (L7) comprises a freeform curved surface; the focal length of the whole image pickup optical camera (10) is f, the focal length of the fourth lens (L4) is f4, the axial thickness of the third lens (L3) is d5, an axial distance between the image side surface of the third lens (L3) and the object side surface of the fourth lens (L4) is d6, and the following relational expressions are satisfied: -4.50≤f4/f≤-2.00, and 0.65≤d5/d6≤19.50. The image pickup optical camera (10) has good optical performance, and satisfies the design requirements of ultra-thinness and a wide angle.
(FR) L'invention concerne une caméra optique de capture d'image (10). D'un côté objet à un côté image, la caméra optique de capture d'image (10) comprend séquentiellement sept lentilles, i.e., une première lentille (L1), une deuxième lentille (L2), une troisième lentille (L3), une quatrième lentille (L4), une cinquième lentille (L5), une sixième lentille (L6) et une septième lentille (L7) ; au moins l'une de la première lentille (L1) à la septième lentille (L7) comprend une surface incurvée de forme libre ; la distance focale de l'intégralité de la caméra optique de capture d'image (10) est f, la distance focale de la quatrième lentille (L4) est f4, l'épaisseur axiale de la troisième lentille (L3) est d5, une distance axiale entre la surface côté image de la troisième lentille (L3) et la surface côté objet de la quatrième lentille (L4) est d6, et les expressions relationnelles suivantes sont satisfaites : -4,50≤f4/f≤-2,00, et 0,65≤d5/d6≤19,50. La caméra optique de capture d'image (10) présente une bonne performance optique et satisfait les exigences de conception d'ultra-minceur et de grand angle.
(ZH) 一种摄像光学镜头(10),摄像光学镜头(10)共包含七片透镜,七片透镜自物侧至像侧依序为:第一透镜(L1),第二透镜(L2),第三透镜(L3),第四透镜(L4),第五透镜(L5),第六透镜(L6),以及第七透镜(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)整体的焦距为f,第四透镜(L4)的焦距为f4,第三透镜(L3)的轴上厚度为d5,第三透镜(L3)的像侧面到第四透镜(L4)的物侧面的轴上距离为d6,且满足下列关系式:-4.50≤f4/f≤-2.00;0.65≤d5/d6≤19.50。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。
