Abstract

The invention relates to the technical field of lenses, and discloses an optical imaging lens. The optical imaging lens comprises ten lenses. The first lens, the second lens, the sixth lens and the ninth lens are convexo-convex lenses with a positive refractive power, and the third lens and the fifth lens are concavo-concave lenses with a negative refractive index, the fourth lens is a plano-convex lens with the positive refractive index, the seventh lens is a concave-convex lens with the negative refractive index, the eighth lens is a convex-concave lens with the negative refractive index, and the tenth lens is a concavo-concave lens or concave-convex lens with the negative refractive index. The image side surface of the second lens and the object side surface of the third lens are gluedto each other; the image side surface of the fourth lens and the object side surface of the fifth lens are glued to each other; the image side surface of the sixth lens and the object side surface ofthe seventh lens are glued to each other; and the image side surface of the eighth lens and the object side surface of the ninth lens are glued to each other. The optical imaging lens has the advantages of a large image surface, a high ratio of unit pixel, large light transmission, good chromatic aberration optimization and good imaging quality.

Description

technical field

[0001] The invention belongs to the field of lens technology, and in particular relates to an optical imaging lens used in an intelligent traffic system. Background technique

[0002] With the continuous advancement of science and technology, in recent years, optical imaging lenses have also developed rapidly, and are widely used in various fields such as smart phones, tablet computers, video conferencing, vehicle monitoring, security monitoring, intelligent transportation systems, etc. Therefore, for optical The requirements for imaging lenses are also getting higher and higher.

[0003] In intelligent transportation systems, the performance of optical imaging lenses is critical and will affect the reliability of the entire system. However, the optical imaging lenses currently used in intelligent transportation systems have a low ratio of unit pixels (pixels), which is not conducive to the development of later algorithms; the general light transmission is r...
