Abstract
(EN)
Disclosed is an optical camera lens (10), sequentially comprising from an object side to an image side: an aperture (S1), a first lens (L1) with a positive refractive power, a second lens (L2) with a positive refractive power, a third lens (L3) with a negative refractive power, a fourth lens (L4) with a negative refractive power, a fifth lens (L5) with a positive refractive power, and a sixth lens (L6) with a negative refractive power, wherein the on-axis thickness of the first lens (L1) is d1, the on-axis distance from an image side face of the first lens (L1) to an object side face of the second lens (L2) is d2, the Abbe number of the first lens (L1) is v1, and the Abbe number of the third lens (L3) is v3. The following relationships are satisfied: 8.00 ≤ d1/d2 ≤ 12.00, and 2.80 ≤ v1/v3 ≤4.00. The optical camera lens (10) has a good optical performance and also satisfies a design requirement for ultra-thinness.

L'invention concerne une lentille de caméra optique (10), comprenant séquentiellement d'un côté objet à un côté image : une ouverture (S1), une première lentille (L1) ayant une réfringence positive, une seconde lentille (L2) ayant une réfringence positive, une troisième lentille (L3) ayant une réfringence négative, une quatrième lentille (L4) ayant une réfringence négative, une cinquième lentille (L5) ayant une réfringence positive, et une sixième lentille (L6) ayant une réfringence négative, l'épaisseur sur l'axe de la première lentille (L1) étant d1, la distance sur l'axe à partir d'une face côté image de la première lentille (L1) à une face côté objet de la deuxième lentille (L2) est d2, le nombre d'Abbe de la première lentille (L1) est v1, et le nombre d'Abbe de la troisième lentille (L3) est v3. Les relations suivantes sont satisfaites : 8,00 ≤ d1/d2 ≤ 12,00, et 2,80 ≤ v1/v3 ≤ 4,00. La lentille de caméra optique (10) a une bonne performance optique et satisfait également une exigence de conception pour une ultra-minceur.
