Abstract

An imaging lens comprises a first lens group, a second lens group, a third lens group, a fourth lens group, a fifth lens group, a sixth lens group and a first reflection assembly. The first lens group has negative refractive power. The second lens group has positive refractive power. The third lens group has negative refractive power. The fourth lens group has positive refractive power. The fifth lens group has refractive power. The sixth lens group has refractive power. The first reflection assembly comprises a first reflection surface. The first lens group, the second lens group, the third lens group, the fourth lens group, the fifth lens group and the sixth lens group are sequentially arranged from the first side to the second side along an axis. The first reflection assembly is arranged between the first lens group and the sixth lens group.

Description

technical field [0001] The present invention relates to an imaging lens. Background technique [0002] The total length of the optical zoom lens is significantly longer than that of the fixed focal length lens, and as the magnification increases, the total length of the lens becomes longer. Today's smart phones that are light and thin cannot be equipped with optical zoom lenses of traditional architecture. Therefore, another imaging lens with a new architecture is required to meet the requirements of miniaturization, high resolution and optical zoom function at the same time, in order to meet the demand for optical zoom function of smart phones. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide an imaging lens with a shorter overall lens length and a thinner lens thickness in view of the defect that the imaging lens in the prior art cannot satisfy miniaturization, high resolution and optical zoom function at the sam...
