Abstract
(EN)
An optical imaging lens, sequentially comprising, from an object side to an image side along an optical axis, a first lens (E1) having positive focal power; a second lens (E2) having negative focal power; a third lens (E3) having focal power; a fourth lens (E4) having focal power, an object side surface (S8) being a convex surface; and a fifth lens (E5) having negative focal power, an image side surface (S10) is a concave surface, wherein a total effective focal length f of the optical imaging lens satisfies the condition that 12 mm(FR)
L'invention concerne une lentille d'imagerie optique, comprenant séquentiellement, d'un côté objet à un côté image le long d'un axe optique, une première lentille (E1) ayant une puissance focale positive; une deuixème lentille (E2) ayant une puissance focale négative; une troisième lentille (E3) ayant une puissance focale; une quatrième lentille (E4) ayant une puissance focale, une surface côté objet (S8) étant une surface convexe; et une cinquième lentille (E5) ayant une puissance focale négative, une surface côté image (S10) étant une surface concave, une longueur focale effective totale f de la lentille d'imagerie optique satisfaisant la condition 12 mm(ZH)
