Optical lens group and optical lens

Abstract

The invention discloses an optical lens group and an optical lens. The optical lens group comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, an eighth lens, a ninth lens and a tenth lens which are sequentially arranged from an object side to an image side, and the object side surface of the first lens to the image side surface of the tenth lens are aspheric surfaces; each of the first lens, the second lens, the fourth lens and the fifth lens has positive refractive power, the object side surface of each lens is a convex surface, and the image side surface of each lens is a concave surface. The third lens element with positive refractive power has a convex object side surface. Each of the sixth lens to the tenth lens has negative refractive power, the object side surfaces ofthe sixth lens to the tenth lens are concave surfaces, and the image side surfaces ofthe sixth lens to the tenth lens are convex surfaces. According to the invention, through reasonable configuration of the surface shape structures of the lenses, balance among requirements of imaging quality, volume or visual angle and the like can be realized, high-definition imaging is realized, miniaturization of the lens can be realized, and the optical lens group has a relatively large visual angle, so that the optical lens group has better optical performance.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to an optical lens group and an optical lens. Background technique [0002] With the popularity of portable electronic devices with camera functions, people have higher and higher requirements for imaging quality of camera lenses of electronic devices. Today's electronic equipment tends to be ultra-thin, and the size of the photosensitive element installed in it is getting smaller and smaller, which correspondingly has higher requirements for the camera lens. [0003] In order to provide higher imaging quality, in the prior art, the number of lenses included in the camera lens is also increasing, and the camera lens with seven lenses is widely used. The imaging quality of this seven-lens camera lens is still limited, and it is difficult to meet the imaging quality requirements of today's consumer market. If the number of lenses is further increased, how to achieve a balance...
