Abstract

The invention provides an optical lens, which comprises in sequence from the object side to the imaging surface along the optical axis: a diaphragm; a first lens with positive refractive power, whose object side is convex; a second lens with negative refractive power, whose object The side surface is concave; the third lens with positive power has a convex surface on the near optical axis; the fourth lens with negative power has a convex surface on the object side; the fifth lens has positive power and its The object side is concave at the near optical axis; the sixth lens with negative refractive power, its object side is concave at the near optical axis; the optical lens meets: 1.85<f / EPD<2.0, 1.35<TTL / ImgH<1.5 ; Wherein, f, EPD and ImgH are respectively the total effective focal length of the optical lens, the diameter of the entrance pupil, half of the diagonal length of the effective pixel area on the imaging surface, and TTL is the distance from the object side of the first lens to the imaging surface on the optical axis distance, so that it has the functions of large aperture, ultra-high pixel, and ultra-thin.

Description

technical field [0001] The invention relates to the technical field of lens imaging, in particular to an optical lens. Background technique [0002] At present, with the popularization of portable electronic devices (such as smartphones, tablets, and cameras), coupled with the popularity of social, video, and live broadcast software, people are more and more fond of photography, and camera lenses have become the standard of electronic equipment. Matching, camera lenses have even become the primary considerations for consumers when purchasing electronic equipment. [0003] With the continuous development of mobile information technology, portable electronic devices such as mobile phones are also developing in the direction of ultra-thin, ultra-high-definition, and the same image quality day and night; The function of the lens needs to have a large aperture characteristic, and the large aperture characteristic is the focus of attention when buying a mobile phone. Thinness an...
