Abstract
(EN) A camera optical lens, sequentially comprising, from an object side to an image side, a first lens (L1) having a negative refractive power, a second lens (L2) having a positive refractive power, a third lens (L3) having a negative refractive power, a fourth lens (L4) having a positive refractive power and a fifth lens (L5) having a negative refractive power, wherein the overall focal length of the camera optical lens is f, the focal length of the second lens (L2) is f2, the focal length of the third lens (L3) is f3, the radius of curvature of an object-side face of the fourth lens (L4) is R7, the radius of curvature of an image-side face of the fourth lens (L4) is R8, the on-axis thickness of the second lens (L2) is d3, and the on-axis thickness of the third lens (L3) is d5; and the following relational expressions are satisfied: 0.95 ≤ f2/f ≤ 2.00; -2.80 ≤ f3/f ≤ -1.50; 4.12 ≤ (R1 + R2)/(R1 - R2) ≤ 26.82; 3.20 ≤ R7/R8 ≤ 6.00; and 1.80 ≤ d3/d5 ≤ 3.50. The camera optical lens meets the design requirements of a large aperture, a wide angle and ultra-thinness, and has a good optical performance.
(FR) L'invention concerne une lentille optique de dispositif de prise de vues, comprenant séquentiellement, d'un côté objet à un côté image, une première lentille (L1) ayant une réfringence négative, une deuxième lentille (L2) ayant une réfringence positive, une troisième lentille (L3) ayant une réfringence négative, une quatrième lentille (L4) ayant une réfringence positive et une cinquième lentille (L5) ayant une réfringence négative, la longueur focale totale de la lentille optique de dispositif de prise de vues étant f, la longueur focale de la deuxième lentille (L2) étant f2, la longueur focale de la troisième lentille (L3) étant f3, le rayon de courbure d'une face côté objet de la quatrième lentille (L4) étant R7, le rayon de courbure d'une face côté image de la quatrième lentille (L4) étant R8, l'épaisseur axiale de la deuxième lentille (L2) étant d3 et l'épaisseur axiale de la troisième lentille (L3) étant d5 ; et les expressions de relation suivantes étant satisfaites : 0,95 ≤ f2/f ≤ 2,00 ; -2,80 ≤ f3/f ≤ -1,50 ; 4,12 ≤ (R1 + R2)/(R1 - R2) ≤ 26,82 ; 3,20 ≤ R7/R8 ≤ 6,00 ; et 1,80 ≤ d3/d5 ≤ 3,50. La lentille optique de dispositif de prise de vues répond aux exigences de conception d'une grande ouverture, d'un grand angle et d'une ultra-minceur tout en ayant une bonne performance optique.
