Abstract

The invention provides an optical imaging lens. From the object side of the optical imaging lens to the image side of the optical imaging lens, the optical imaging lens sequentially comprises: a first lens, wherein the first lens has positive focal power, and the image side surface of the first lens is a convex surface; a second lens, wherein the second lens has positive focal power; a third lens; a fourth lens; and a fifth lens element. The on-axis distance TTL from the object side surface of the first lens to the imaging surface of the optical imaging lens and half of the diagonal line length ImgH of an effective pixel area on the imaging surface of the optical imaging lens meet the condition that 0.9<TTL / ImgH<1.4; and the maximum half field angle Semi-FOV of the optical imaging lens meets the condition that 50 degrees <Semi-FOV<60 degrees. The optical imaging lens solves the problem that an optical imaging lens in the prior art cannot give consideration to both a large field angle and miniaturization.

Description

technical field [0001] The present invention relates to the technical field of optical imaging equipment, in particular to an optical imaging lens. Background technique [0002] Due to the fast iterative speed of electronic devices such as smart phones, the market demand has steadily increased, and a single mobile phone is usually equipped with 2-8 camera lenses, usually including large aperture, super wide-angle, telephoto, optical image stabilization and large image area. Functional optical imaging lenses greatly enrich people's choices. Among them, the front camera module introduces a wide-angle lens, which can capture object information with a larger field of view than conventional lenses, so it can accommodate more details of people when taking selfies. The optical imaging lens is made thinner and lighter, but this will sacrifice the imaging quality of the optical imaging lens. [0003] That is to say, the optical imaging lens in the prior art has the problem that a l...
