Optical imaging camera lens

Abstract

The invention discloses an optical imaging camera lens. The optical imaging camera lens comprises, sequentially from an object side to an image side, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens, and is capable of satisfying following conditional expressions: 1.30 is smaller than or equal to T1 / (T3+T4); ALT / Gmax is smaller than or equal to 2.30. The optical imaging camera lens is used for the optical shooting imaging, and by controlling the arrangement of the concave surfaces and the convex surfaces of the various lenses and adopting at least two conditional expressions to control related parameters, good optical performance is maintained, and the length of the camera lens is reduced under a condition of increasing effective focal length of a system and reducing a field angle.

Description

technical field [0001] The present invention is related to an optical imaging lens, and especially an optical imaging lens using a six-piece lens. Background technique [0002] The specifications of consumer electronic products are changing with each passing day, and the pace of pursuit of lightness, thinness and compactness has not slowed down, and the demand for telephoto features has even begun to be added. Therefore, the specifications of key components of electronic products such as optical lenses must continue to improve in order to meet the needs of consumer electronics. needs of the reader. The most important characteristics of optical lenses are nothing more than image quality and volume. Among them, in terms of imaging quality, with the advancement of image sensing technology, consumers' requirements for imaging quality will also increase. Therefore, in the field of optical lens design, in addition to pursuing thinner lenses, lens imaging must also be considered. ...

AI Technical Summary

Problems solved by technology

In terms of a six-element lens structure, in previous inventions, the distance from the object side of the first lens to the imaging surface on the optical axis is large, which is not conducive to the thinning of mobile phones and digital cameras

[0003] However, optical lens design does not simply reduce the proportion of a lens with good imaging quality to produce an optical lens with both image quality and miniaturization. The design process not only involves material characteristics, but also production and assembly yields. practical problems

[0004] In addition, the longer the focal length of the lens, the greater the magnification of the telephoto lens, so the length of the telephoto lens is not easy to shorten

The conflicting design concepts of shortening the length of the lens and increasing the magnification, coupled with maintaining the image quality, is a very difficult problem in the design of optical imaging lenses
