Abstract

The invention discloses an optical imaging lens. The optical imaging lens comprises a first lens with positive focal power, a second lens with focal power, a third lens with focal power, a fourth lenswith focal power, a fifth lens with positive focal power and a sixth lens with negative focal power from the object side to the image side along an optical axis in sequence. The object side face of the first lens is a convex face. The object side face of the fourth lens is a convex face, and the image side face of the fourth lens is a concave face. The object side face of the sixth lens is a convex face. The distance TTL, between the object side face of the first lens of the optical imaging lens and the imaging face of the optical imaging lens, on the optical axis and a half of diagonal length ImgH of an effective pixel area on the imaging face meet the formula: TTL / ImgH<1.6; the total effective focal length f of the optical imaging lens and the maximum half-field angle Semi-FOV of the optical imaging lens meet the formula: 4.5 millimeters<f*tan(Semi-FOV)<7 millimeters.

Description

technical field [0001] The present application relates to an optical imaging lens, and more particularly, to an optical imaging lens including six lenses. Background technique [0002] With the rapid development of electronic products, imaging lenses are used more and more widely. On the one hand, with the trend of portable electronic products becoming thinner and lighter, the imaging lens must not only have good image quality, but also need to be thin and light, so as to effectively reduce the thickness of portable electronic products. On the other hand, people also put forward higher and higher requirements on the image quality of imaging lenses of portable electronic products. [0003] With the improvement of semiconductor process technology, the pixel size of the photosensitive element is continuously reduced, making the imaging lens mounted on portable electronic products such as mobile phones or digital cameras gradually tend to be miniaturized, with large field of vi...
