Problems solved by technology

[0003] However, in order to achieve the characteristics of large image area, large aperture, and ultra-thin, new challenges have been put forward in the field of lens design. The previous five-element or six-element optical system structure is not enough to meet these challenges. Seven-element The traditional optical imaging system may gradually become the mainstream

Abstract

The invention discloses an optical imaging lens, which sequentially comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens, which have refractive power, along an optical axis from an object side to an image side, wherein the first lens has positive refractive power; the third lens has negative refractive power; half ImgH of the length of adiagonal line of an effective pixel region on an imaging plane of the optical imaging lens meets the condition that ImgH is greater than 5mm; and the relative F number Fno of the optical imaging lensmeets the condition that Fno is smaller than 1.6.

Description

technical field [0001] The present application relates to an optical imaging lens, and more particularly, to an optical imaging lens including seven lenses. Background technique [0002] With the rapid development of portable electronic devices such as smart phones, consumers have higher and higher requirements for matching camera lenses on portable electronic devices. Especially for the main camera lens of smartphones, it is hoped that it can have the characteristics of large image area, large aperture, and ultra-thin at the same time. Large image area means higher pixels and imaging resolution; large aperture represents more effective luminous flux and higher signal-to-noise ratio during imaging, which is conducive to the image quality of night scenes and low light; ultra-thinness can be combined with smart The shape of the mobile phone achieves better compatibility and is easy to carry. Compared with the previous mobile phone lens specifications, changes in these main v...
