Abstract
(EN) An optical camera lens (10), comprising, sequentially from an object side to an image side: a first lens (L1), a second lens (L2), a third lens (L3), a fourth lens (L4), a fifth lens (L5), a sixth lens (L6), a seventh lens (L7) and an eighth lens (L8), wherein the first lens (L1) has a positive refractive power, the optical camera lens (10) has a focal length f, the second lens (L2) has a focal length f2, the optical camera lens (10) has a total optical length TTL, an object side surface of the third lens (L3) has a radius of central curvature R5, an image side surface of the third lens (L3) has a radius of central curvature R6, and the following relational expressions are satisfied: 0.95 ≤ f/TTL; -3.50 ≤ f2/f ≤ -1.80; and 2.50 ≤(R5 + R6)/(R5 - R6) ≤ 20.00. The optical camera lens (10) meets the design requirements of a large aperture, a long focal length and ultra-thin thinness while having good optical properties.
(FR) L'invention concerne une lentille de caméra optique (10), comprenant, séquentiellement d'un côté objet à un côté image : une première lentille (L1), une deuxième lentille (L2), une troisième lentille (L3), une quatrième lentille (L4), une cinquième lentille (L5), une sixième lentille (L6), une septième lentille (L7) et une huitième lentille (L8), la première lentille (L1) ayant une réfringence positive, la lentille de caméra optique (10) ayant une distance focale f, la deuxième lentille (L2) ayant une distance focale f2, la lentille de caméra optique (10) ayant une distance optique totale TTL, une surface côté objet de la troisième lentille (L3) ayant un rayon de courbure centrale R5, une surface côté image de la troisième lentille (L3) ayant un rayon de courbure centrale R6, et les expressions relationnelles suivantes étant satisfaites : 0,95 ≤ f/TTL ; -3,50 ≤ f2/f ≤ -1,80 ; et 2,50 ≤(R5 + R6)/(R5 - R6) ≤ 20,00. La lentille de caméra optique (10) répond aux exigences de conception d'une grande ouverture, d'une longue distance focale et d'une épaisseur ultra-mince tout en ayant de bonnes propriétés optiques.
(ZH) 一种摄像光学镜头(10),自物侧至像侧依序包括: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)以及第八透镜(L8);第一透镜(L1)具有正屈折力;其中,摄像光学镜头(10)的焦距为f,第二透镜(L2)的焦距为f2,摄像光学镜头(10)的光学总长为TTL,第三透镜(L3)物侧面的中心曲率半径为R5,第三透镜(L4)像侧面的中心曲率半径为R6,且满足下列关系式:0.95≤f/TTL;-3.50≤f2/f≤-1.80;2.50≤(R5+R6)/(R5-R6)≤20.00。这种摄像光学镜头(10)具有良好光学性能的同时,满足大光圈、长焦距、超薄化的设计要求。
