Abstract

The invention relates to the technical field of optical imaging and provides a miniature high-resolution aspherical lens group, which comprises six lens sequentially arranged in a direction from the objective side to the image side at intervals; different refractive power, focal lengths and concave-convex surfaces are set for each lens; the ratio of the sum of the thickness values of the second lens and the third lens to the thickness of the first lens is between 0.8 and 1.0. Compared with the prior art, the miniature high-resolution aspherical lens group provided by the invention has the advantages that the six lens are sequentially arranged in a setting direction at intervals; each lens is provided with different refractive power and concave-convex surfaces. Therefore the miniature high-resolution aspherical lens group provided by the invention is provided with the six lens, so that the high-quality imaging of the optical lens group is realized; meanwhile, the structure of the optical lens group is simple and thinner; good market prospects are realized.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to a miniaturized high-resolution aspheric lens group and an imaging system. Background technique [0002] As imaging electronic products are used more and more widely, and people carry them with them more and more frequently, this type of imaging camera is required to be made smaller in size and lighter in weight. At the same time, its imaging quality is also one of the goals people pursue. [0003] The imaging function of electronic products is limited by early technology and processing, and the volume of the produced products is often large, and the imaging quality is not good. With the development of the imaging camera market, the pursuit of simple and thin volume and high-quality imaging requirements is now required. However, the lens structure with fewer pieces cannot meet the requirements of consumers. Therefore, how to use the camera lens composed of six lenses to...
