Abstract

The invention provides an optical imaging lens. The optical imaging lens sequentially comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens from an object side to an image side along an optical axis. The first lens has focal power, the second lens has negative focal power, the third lens has focal power, the fourth lens has negative focal power, the fifth lens has negative focal power, the sixth lens has focal power, the object side surface of the sixth lens is a concave surface, and the image side surface of the sixth lens is a convex surface, and the seventh lens has focal power; the distance TTL from the object side surface of the first lens to the imaging surface along the optical axis and the total effective focal length f of the optical imaging lens satisfy TTL/f < 1, and the half ImgH of the diagonal length of the effective pixel region on the imaging surface and the maximum half field angle Semi-FOV of the optical imaging lens satisfy 8mm < ImgH/tan (Semi-FOV).

Description

technical field [0001] The present application relates to the field of optical elements, more specifically, to an optical imaging lens. Background technique [0002] In recent years, various portable electronic products such as smart phones have been developed by leaps and bounds, and higher requirements are put forward for optical imaging lenses mounted on portable electronic products. The telephoto lens has high practicability in the actual shooting process. In addition to the angle of view and blur, the telephoto lens can also cause the illusion of perspective. Therefore, it has been favored by more and more consumers and has gradually become the standard configuration of mobile phone lenses. [0003] However, conventional telephoto lenses often cannot meet the constantly updated design requirements of electronic products, and their structures need to be improved and optimized. In the case of ensuring the structural manufacturability, how to make the telephoto lens take ...
