Abstract

The invention provides an optical imaging lens. The optical imaging lens comprises a first lens with positive refractive power, 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; the object side surface of the second lens is a convex surface, and the image side surface of the second lens is a concave surface; a third lens element with negative refractive power; a fourth lens element with positive refractive power; the fifth lens has negative refractive power, the object side surface of the fifth lens is a convex surface, and the image side surface of the fifth lens is a concave surface; a sixth lens element with positive refractive power, wherein the object-side surface of the sixth lens element is a convex surface; the object side surface of the seventh lens is a concave surface, and the image side surface of the seventh lens is a concave surface; the half ImgH of the diagonal length of an effective pixel area on the imaging surface of the optical imaging lens and the on-axis distance TTL from the object side surface of the first lens to the imaging surface meet the following conditions: 4.7 mmlt; imgH * ImgH / TTL < lt >; and 5.7 mm. The optical imaging lens solves the problem that high image quality and miniaturization of an optical imaging lens in the prior art are difficult to consider at the same time.

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] Recently, the requirements for mobile terminals are getting higher and higher, and the trend of high-definition mobile terminals is becoming more and more obvious with the continuous upgrading of market demand and module technology, which leads to higher and higher requirements for the imaging quality of imaging lenses. , and at the same time, the weight of the mobile terminal is required to be lighter and lighter, and it is difficult for the optical imaging lens in the prior art to balance high image quality and miniaturization. [0003] That is to say, the optical imaging lens in the prior art has the problem that it is difficult to balance high image quality and miniaturization. Contents of the invention [0004] The main purpose of the present invention is to provide an optical imaging lens to...
