Problems solved by technology

[0003] The known optical imaging lenses are mostly four-piece optical imaging lenses. Due to the small number of lenses, the length of optical imaging lenses can be shortened. However, with the increasing demand for high-standard products, optical imaging lenses are used in The demand for picture quality and quality is rapidly increasing, and it is extremely necessary to develop products with higher specifications, such as optical imaging lenses using a six-element lens structure. However, known six-element lenses are shown in US Patent Nos. US7663814 and US8040618. The length is as high as 21mm or more, which is not conducive to the thinning of mobile phones and digital cameras, so it is extremely necessary to develop a lens with good image quality and shortened lens length

Embodiment Construction

[0105] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0106] Before the present invention is described in detail, it should be noted that in the following description, similar components are denoted by the same numerals.

[0107] The term "a lens has positive refractive power (or negative refractive power)" in this specification means that the lens has positive refractive power (or negative refractive power) in the vicinity of the optical axis. "The object side (or image side) of a lens has a convex surface (or concave surface) located in a certain area" means that the area is closer to the direction parallel to the optical axis than the radially outer area of ​​the area. For "convex" (or "concave"), the figure 1 For example, where I is the optical axis and the lens is radially symmetrical to each other with the optical axis I as the axis of symmetry, the object side of the lens has a convex surface in...

Abstract

An imaging lens includes an aperture stop and first to sixth lens elements arranged from an object side to an image side in the given order. Through designs of surfaces of the lens elements and relevant optical parameters, a short system length of the imaging lens may be achieved while maintaining good optical performance.

Description

technical field [0001] The invention relates to an optical lens, in particular to a six-piece optical imaging lens and an electronic device using the lens. Background technique [0002] In recent years, the popularity of portable electronic products such as mobile phones and digital cameras has led to the vigorous development of related technologies of image modules (mainly including optical imaging lenses, module holder units, and sensors). The trend of thinner and lighter also makes the demand for miniaturization of image modules higher and higher. With the technological progress and size To reduce the size, the length of the optical imaging lens loaded in the image module also needs to be shortened accordingly. However, in order to avoid the reduction of photographic effect and quality, good optical performance must still be taken into account when shortening the length of the optical imaging lens. [0003] The known optical imaging lenses are mostly four-piece optical i...
