Miniature high-definition lens group and imaging system

Abstract

The invention relates to the technical field of optical imaging and provides a miniature high-definition lens group. 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 the thickness value of the second lens to the thickness value of the third lens is between 0.8 and 1.1. Compared with the prior art, the miniature high-definition lens group 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 miniature high-definition lens group 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 miniaturized high-definition lens group and an imaging system. Background technique [0002] At present, the competition in the imaging lens market is becoming more and more fierce. The lenses produced by major manufacturers are all developing in the direction of miniaturization, and the imaging lenses have also become the standard configuration of many electronic products. Moreover, the volume of these lenses is also required to be manufactured in the direction of miniaturization, and the imaging quality requirements are getting higher and higher. [0003] However, many imaging lenses on the market use four or five elements for imaging. Although they can basically meet the imaging requirements, they cannot meet the higher imaging requirements. The problem that needs to be solved at present is that the volume of the imaging lens is large, resulting in a large volume of...

Problems solved by technology

[0003] However, many imaging lenses on the market use four or five elements for imaging. Although they can basically meet the imaging requirements, they cannot meet the higher imaging requirements.

The problem that needs to be solved at present is that the volume of the imaging lens is large, resulting in a large volume of electronic products. In order to improve the competitiveness of this type of electronic products, it is necessary to further reduce the volume of these imaging lenses and improve the imaging quality
