Embodiment Construction

[0084] To further illustrate the various embodiments, the present invention is provided with accompanying drawings. These drawings are a part of the disclosure of the present invention, which are mainly used to illustrate the embodiments, and can be combined with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should understand other possible implementations and advantages of the present invention. Components in the figures are not drawn to scale, and similar component symbols are generally used to denote similar components.

[0085] 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 area near the optical axis. "The object side (or image side) of a lens includes a convex surface (or concave surface) in a certain area" means that...

Abstract

Present embodiments provide for a mobile device and an optical imaging lens thereof. The optical imaging lens comprises six lens elements positioned sequentially from an object side to an image side. Through controlling the convex or concave shape of the surfaces of the lens elements and designing parameters satisfying at least one inequality, the optical imaging lens shows better optical characteristics and the total length of the optical imaging lens is shortened.

Description

technical field [0001] The present invention is related to a portable electronic device and its optical imaging lens, and especially related to a portable electronic device using a six-piece lens and its optical imaging lens. Background technique [0002] In recent years, the popularization of mobile phones and digital cameras has led to the vigorous development of photographic modules including optical imaging lenses, lens barrels, and image sensors. The thinner and lighter mobile phones and digital cameras have also increased the demand for miniaturization of photographic modules. With the technological progress and size reduction of the photosensitive coupling device (Charge Coupled Device, referred to as CCD) or complementary metal oxide semiconductor device (Complementary Metal-Oxide Semiconductor, referred to as CMOS), the optical imaging lens installed in the camera module also needs to be reduced in size, but the optical imaging lens Good optical performance is also ...
