Abstract

The invention relates to the technical field of optical imaging and provides a lens group with a small size and high imaging quality. The lens group comprises six lenses arranged from an object side to an image side successively at intervals. The lenses have different refractive power, focal lengths, and concave-convex surfaces. A ratio of a distance value between the first lens and an imaging surface to the thickness value of the second lens is between 14 and 17. Compared with the prior art, the lens group with the small size and high imaging quality provides the lenses with different refractive power and concave-convex surfaces by arranging the six lenses successively at intervals along a direction. Thus, by arranging the six lenses, the lens group with the small size and high imaging quality realizes high-quality imaging, takes account of simple and compact structure, and has good market prospect.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to a lens group and an imaging system with a small volume and high imaging quality. Background technique [0002] At present, with the development of electronic products, more and more people are used to using various electronic products and carrying them with them for travel. The trend for the development of these electronic products is to reduce the weight, which is convenient for people to carry. Many of these electronic products have lenses for imaging. And these lenses are also required to be lightweight to facilitate portability; on the other hand, people are also demanding higher and higher imaging quality. [0003] Although many imaging lenses on the market use four-element or five-element lenses for imaging, generally the highest imaging pixels are at the million level. Although they can meet the general imaging quality requirements, they cannot go further to achi...
