Abstract

The present application discloses an optical imaging lens, which includes sequentially from the object side to the image side along the optical axis: a first lens with negative refractive power, whose object side is concave and the image side is concave; Two lenses; a third lens with optical power; a fourth lens with optical power; a fifth lens with optical power whose image side is convex; and a sixth lens with optical power. The maximum field of view FOV of the optical imaging lens satisfies: 100°<FOV<140°. The TV distortion TVD of the optical imaging lens satisfies: |TVD|<1.1%. The half of the diagonal length of the effective pixel area on the imaging surface of the optical imaging lens, ImgH, and the distance TTL from the object side of the first lens to the imaging surface along the optical axis satisfy: 0.3<ImgH / TTL<1.3.

Description

technical field [0001] The present application relates to the field of optical components, and more particularly, to an optical imaging lens. Background technique [0002] With the rapid development of science and technology in the 21st century, the development of miniature cameras suitable for portable electronic products such as mobile phones and tablet computers is also changing with each passing day, and people's requirements for the imaging quality of camera lenses are also getting higher and higher. In order to improve competitiveness, electronic product manufacturers often use multiple cameras to meet people's requirements in different scenarios. For example, many mobile phones use dual, triple, or even quad and five cameras, which generally include telephoto, Wide-angle, large image area and other lenses. Wide-angle lens has the characteristics of large viewing angle and long depth of field, which can accommodate more scenery in the picture, and has an irreplaceable...
