Abstract

The invention provides an optical imaging lens. From the object side to the image side of the optical imaging lens, the optical imaging lens sequentially comprises a first lens with positive focal power, wherein the object side surface of the first lens is a convex surface, and the image side surface of the first lens is a concave surface; a second lens, which has negative focal power; a third lens, which has positive focal power; a fourth lens, which has negative focal power; a fifth lens, which has positive focal power; a sixth lens, which has negative focal power; a seventh lens, which has positive focal power, wherein the object side surface is a convex surface, and the image side surface is a concave surface; an eighth lens, which has negative focal power, wherein the object side surface is a convex surface; the Abbe number V1 of the first lens is more than 60 and less than 90; and the effective focal length f of the optical imaging lens and the maximum field angle FOV of the optical imaging lens meet the following condition: 7.0 mm < f * tan (FOV / 2) < 9.0 mm. The problem that in the prior art, an optical imaging lens is poor in imaging quality is solved.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to an optical imaging lens. Background technique [0002] With the popularization of mobile phone cameras, the functions of mobile phone cameras are becoming more and more diverse, and major terminal manufacturers have higher and higher requirements for lens design. The current terminal products are generally equipped with three or four lenses, one of which is the main camera lens, and manufacturers are improving the imaging quality of the main camera lens. [0003] That is to say, the optical imaging lens in the prior art has the problem of poor imaging quality. Contents of the invention [0004] The main purpose of the present invention is to provide an optical imaging lens to solve the problem of poor imaging quality of the optical imaging lens in the prior art. [0005] In order to achieve the above object, according to one aspect of the present invention, an optical...
