Abstract
(EN)
Disclosed is an optical lens group, the lens group sequentially comprising from an object side to an image side along an optical axis: a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens, wherein the first lens has negative focal power; the second lens has negative focal power; the third lens has positive focal power; the fourth lens has positive focal power; the fifth lens has focal power, and an object side surface thereof is a convex surface; and the sixth lens has positive focal power. The maximum semi-field of view (semi-FOV) of the optical lens group and the maximum incident angle CRAmax of a main light ray of the optical lens group incident to an electronic photosensitive component satisfy 5 < semi-FOV/CRAmax < 10.

L'invention concerne un groupe de lentilles optiques, le groupe de lentilles comprenant séquentiellement d'un côté objet à un côté image le long d'un axe optique : une première lentille, une deuxième lentille, une troisième lentille, une quatrième lentille, une cinquième lentille et une sixième lentille, la première lentille ayant une puissance focale négative ; la deuxième lentille ayant une puissance focale négative ; la troisième lentille ayant une puissance focale positive ; la quatrième lentille ayant une puissance focale positive ; la cinquième lentille ayant une puissance focale, et une surface côté objet de celle-ci étant une surface convexe ; et la sixième lentille ayant une puissance focale positive. Le demi-champ de vision maximal (semi-FOV) du groupe de lentilles optiques et l'angle d'incidence maximal CRAmax d'un rayon lumineux principal du groupe de lentilles optiques incident sur un composant électronique photosensible satisfont 5 < semi-FOV/CRAmax < 10.
