Abstract

The invention provides an optical imaging lens. The optical imaging lens comprises a first lens with negative focal power; a second lens with positive focal power, wherein 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; a fourth lens with positive focal power; a fifth lens; and a sixth lens with negative focal power; wherein the half of the diagonal length ImgH of an effective pixel area on the imaging surface of the optical imaging lens, the effective focal length f of the optical imaging lens and the aperture value Fno of the optical imaging lens meet the following condition that ImgH / (f*Fno) is larger than 0.3 and smaller than 0.55; the on-axis distance TTL from the object side face to the imaging face of the first lens, the maximum half-field angle Semi-FOV of the optical imaging lens and the entrance pupil diameter EPD of the optical imaging lens meet the condition that TTL* tan(Semi-FOV) / EPD is larger than 5.5 and smaller than 7.5. The problem that an optical imaging lens in the prior art is large in size is solved.

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] At present, the electronic product market is developing rapidly, and people's pursuit of the electronic market is no longer limited to cameras and mobile phones in the traditional sense. In recent years, people's enthusiasm for wearable devices has continued to rise. As a convenient and convenient wearable device, smart watches can not only tell the time, call for help, monitor heart rate, but also be used for taking pictures, video calls, etc. The space is also relatively small, but the optical imaging lens is relatively large. [0003] That is to say, the optical imaging lens in the prior art has the problem of large volume. Contents of the invention [0004] The main purpose of the present invention is to provide an optical imaging lens to solve the problem of large volume of the optical imagi...
