Abstract
(EN) A camera optical lens (10, 20, 30), which relates to the field of optical lenses, comprises nine lenses in total, namely, from an object side to an image side, a first lens (L1) having a positive refractive power, a second lens (L2), a third lens (L3), a fourth lens (L4), a fifth lens (L5), a sixth lens (L6), a seventh lens (L7), an eighth lens (L8) and a ninth lens (L9) in sequence, wherein the second lens (L2) has a negative refractive power, the optical camera lenses (10, 20, 30) have a focal length f, the first lens (L1) has a focal length f1, the second lens (L2) has an on-axis thickness d3, the on-axis distance from an image side face of the second lens (L2) to an object side face of the third lens (L3) is d4, and the following relational expressions are met: 2.00 ≤ f1/f ≤ 5.00 and 2.00 ≤ d3/d4 ≤ 10.00. The optical camera lens (10, 20, 30) meets the design requirements of a large aperture, a wide angle, and an ultra-thin thickness, while also having a good optical performance.
(FR) L'invention concerne une lentille optique de caméra (10, 20, 30), qui se rapporte au domaine des lentilles optiques, comprenant neuf lentilles au total, à savoir, d'un côté objet à un côté image, une première lentille (L1) ayant une réfringence positive, une deuxième lentille (L2), une troisième lentille (L3), une quatrième lentille (L4), une cinquième lentille (L5), une sixième lentille (L6), une septième lentille (L7), une huitième lentille (L8) et une neuvième lentille (L9) en séquence, la deuxième lentille (L2) ayant une réfringence négative, les lentilles de caméra optique (10, 20, 30) ayant une distance focale f, la première lentille (L1) ayant une distance focale f1, la deuxième lentille (L2) ayant une épaisseur sur l'axe d3, la distance sur l'axe d'une face côté image de la deuxième lentille (L2) à une face côté objet de la troisième lentille (L3) étant d4, et les expressions relationnelles suivantes étant satisfaites : 2,00 ≤ f1/f ≤ 5,00 et 2,00 ≤ d3/d4 ≤ 10,00. La lentille de caméra optique (10, 20, 30) répond aux exigences de conception d'une grande ouverture, d'un grand angle et d'une épaisseur ultra-mince, tout en ayant une bonne performance optique.
(ZH) 一种摄像光学镜头(10,20,30),涉及光学镜头领域,摄像光学镜头(10,20,30)共其包含九片透镜,九片透镜自物侧至像侧依序为:具有正屈折力的第一透镜(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),第七透镜(L7),第八透镜(L8),以及第九透镜(L9);第二透镜(L2)具有负屈折力;其中,摄像光学镜头(10,20,30)的焦距为f,第一透镜(L1)的焦距为f1,第二透镜(L2)的轴上厚度为d3,第二透镜(L2)的像侧面到第三透镜(L3)的物侧面的轴上距离为d4,且满足下列关系式:2.00≤f1/f≤5.00;2.00≤d3/d4≤10.00。摄像光学镜头(10,20,30)具有良好光学性能的同时,满足大光圈、广角化、超薄化的设计要求。
