Problems solved by technology

[0003] At present, in order to achieve mega-pixel resolution, aspheric surfaces are usually used to correct aberrations including chromatic aberration. High-resolution images can be obtained by increasing the number of lenses to more than 6, but the size and weight of the lens will increase accordingly. This is not conducive to the miniaturization of the lens, and will cause the cost to rise at the same time

Description

technical field [0001] The present application relates to an optical lens, and more particularly, the present application relates to an optical lens including seven lenses. Background technique [0002] With the development of technology, the requirements for optical lenses are constantly increasing. Especially for vehicle-mounted lenses, small distortion, miniaturization, high-resolution, and large-aperture lenses are essential conditions for this type of lens. Especially in terms of resolution requirements, it is gradually improving from the original megapixels to 2M and 4M. [0003] At present, in order to achieve mega-pixel resolution, aspheric surfaces are usually used to correct aberrations including chromatic aberration. High-resolution images can be obtained by increasing the number of lenses to more than 6, but the size and weight of the lens will increase accordingly. This is not conducive to the miniaturization of the lens, and at the same time causes an increas...
