Image Pick-Up Lens System and Module and Terminal Therefor |
摘要 |
The present invention provides an image pick-up lens system, an imaging module having the image pick-up lens system, and a terminal having the imaging module. The image pick-up lens system comprises the following lenses arranged sequentially from an object side to an image side: a first lens with positive focal power; a second lens with negative focal power, having a convex object-side surface; a third lens with negative focal power; a fourth lens with focal power; a fifth lens with positive focal power, having a convex image-side surface; and a sixth lens with focal power, having a concave image-side surface near an optical axis, wherein, the lenses meet the following relational expression: 5.5<f1.2.3/Dr1r6<10, where, f1.2.3 is a combined focal length of the first lens, second lens, and third lens; Dr1r6 is a spacing from an object-side surface of the first lens to an image-side surface of the third lens on the optical axis. The lens system provided in the present invention employs six plastic aspherical lenses; by menas of a proper focal power allocation and in a large aperture diameter configuration, the length of the lens system is effectively shortened, the aberration influence is reduced, and the imaging quality of the lens system is improved. |
