Title
(EN) CAMERA OPTICAL LENS
(FR) LENTILLE OPTIQUE DE DISPOSITIF DE PRISE DE VUES
(ZH) 摄像光学镜头
Abstract
(EN)
A camera optical lens, the camera optical lens comprising the following in order from the object side to the image side: a first lens (L1), a second lens (L2), a third lens (L3), a fourth lens (L4), a fifth lens (L5), and a sixth lens (L6); the second lens (L2) has positive refractive power, and the third lens (L3) has positive refractive power; and the following relationships are met: 4.00≤f1/f≤7.00; -20.00≤R9/d9≤-9.00. The described camera optical lens is capable of achieving high imaging performance while having low TTL.
(FR)
L'invention concerne une lentille optique de dispositif de prise de vues. La lentille optique du dispositif de prise de vues comprend les éléments suivants, dans l'ordre depuis le côté objet vers le côté image, une première lentille (L1), une deuxième lentille (L2), une troisième lentille (L3), une quatrième lentille (L4), une cinquième lentille (L5) et une sixième lentille (L6); la deuxième lentille (L2) a une réfringence positive et la troisième lentille (L3) a une réfringence positive; et les relations suivantes sont satisfaites : 4,00 ≤ f1/f ≤ 7,00; -20,00 ≤ R9/d9 ≤ -9,00. La lentille optique du dispositif de prise de vues décrite est capable d'atteindre une performance d'imagerie élevée tout en ayant une TTL faible.
