Abstract
(EN)
Disclosed in the present application is an optical imaging lens. The imaging lens successively comprises, along an optical axis from an object side to an image side: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens. The first lens has a negative focal power; the second lens has a negative focal power; the third lens has a positive focal power; the fourth lens has a positive focal power; the fifth lens has a focal power and an object side surface thereof is concave; the sixth lens has a focal power; and the seventh lens has a negative focal power. An effective focal length f1 of the first lens and a total effective focal length f of the optical imaging lens satisfy −3.5(FR)
La présente invention concerne une lentille d'imagerie optique. La lentille d'imagerie comprend successivement, le long d'un axe optique d'un côté objet à un côté image : une première lentille, une deuxième lentille, une troisième lentille, une quatrième lentille, une cinquième lentille, une sixième lentille et une septième lentille. La première lentille a une puissance focale négative; la deuxième lentille a une puissance focale négative; la troisième lentille a une puissance focale positive; la quatrième lentille a une puissance focale positive; la cinquième lentille a une puissance focale et une surface côté objet de celle-ci est concave; la sixième lentille a une puissance focale; et la septième lentille a une puissance focale négative. Une distance focale effective f1 de la première lentille et une distance focale effective totale f de la lentille d'imagerie optique satisfont −3.5(ZH)
本申请公开了一种光学成像镜头,该成像镜头沿着光轴由物侧至像侧依序包括:第一透镜、第二透镜、第三透镜、第四透镜、第五透镜、第六透镜和第七透镜。第一透镜具有负光焦度;第二透镜具有负光焦度;第三透镜具有正光焦度;第四透镜具有正光焦度;第五透镜具有光焦度,其物侧面为凹面;第六透镜具有光焦度;第七透镜具有负光焦度。第一透镜的有效焦距f1与光学成像镜头的总有效焦距f满足-3.5<f1/f<0。
