Abstract
(EN)
Provided is an optical imaging lens comprising, in order from the object side to the image side along the optical axis: a first lens (E1), a second lens (E2), a third lens (E3), a fourth lens (E4), a fifth lens (E5), and a sixth lens (E6). The first lens (E1) has a positive focal power, and an object side surface (S1) thereof is a convex surface. The second lens (E2) has a focal power, the object side surface (S3) thereof is a convex surface, and an image side surface (S4) thereof is a concave surface. The third lens (E3) and the fourth lens (E4) each has a focal power. The fifth lens (E5) has a positive focal power, and the image side surface (S10) of the fifth leans (E5) is a convex surface. The sixth lens (E6) has a negative focal power, and both the object side surface (S11) and the image side surface (S12) of the sixth leans (E6) are concave surfaces. The total effective focal length f of the optical imaging lens and the entrance pupil diameter EPD of the optical imaging lens satisfy f/EPD ≤ 1.6.

La présente invention concerne une lentille d'imagerie optique qui comprend dans l'ordre, du côté objet au côté image le long de l'axe optique : une première lentille (E1), une deuxième lentille (E2), une troisième lentille (E3), une quatrième lentille (E4), une cinquième lentille (E5) et une sixième lentille (E6). La première lentille (E1) a une puissance focale positive, et sa surface côté objet (S1) est une surface convexe. La deuxième lentille (E2) a une puissance focale, sa surface côté objet (S3) est une surface convexe, et sa surface côté image (S4) est une surface concave. La troisième lentille (E3) et la quatrième lentille (E4) ont chacune une puissance focale. La cinquième lentille (E5) a une puissance focale positive, et la surface côté image (S10) de la cinquième lentille (E5) est une surface convexe. La sixième lentille (E6) a une puissance focale négative, et la surface côté objet (S11) et la surface côté image (S12) de la sixième lentille (E6) sont des surfaces concaves. La longueur focale effective totale (f) de la lentille d'imagerie optique et le diamètre de pupille d'entrée (EPD) de la lentille d'imagerie optique satisfont à f/EPD ≤ 1,6.
