Problems solved by technology

[0003] Although the common five-element lens already has good optical performance, its focal power, lens spacing and lens shape settings are still unreasonable, resulting in a lens structure that cannot meet the requirements of large aperture, large aperture, and high optical performance while having good optical performance. Ultra-thin, wide-angle design requirements

Abstract

The invention relates to a five-piece type high-pixel imaging lens, and the five-piece type high-pixel imaging lens is composed of five lenses. The five-piece type high-pixel imaging lens sequentially comprises a first lens with positive refraction power, a second lens with negative refraction power, a third lens with positive refraction power or negative refraction power, a fourth lens with positive refraction power and a fifth lens with negative refraction power from an object side to an image side, and meets the following relational expressions: ImgH / Fno is greater than 1.91, wherein ImgH is half of the length of a diagonal line of an effective imaging area of the five-piece type high-pixel imaging lens, and Fno is the aperture number of the five-piece type high-pixel imaging lens. The five-piece type high-pixel imaging lens is high in imaging quality and light and thin in size, and has a large aperture and a large field angle.

Description

technical field [0001] The invention relates to the technical field of optical imaging lenses, in particular to a five-chip high-pixel imaging lens. Background technique [0002] In recent years, the optical imaging lens has been constantly evolving, and its application range is wider. In addition to requiring the lens to be thin and short, the imaging quality of the lens is also required to be higher and higher. In order to improve the imaging quality, it is necessary to increase the number of optical lenses to correct problems such as aberration and dispersion. However, as the number of optical lenses increases, the distance on the optical axis from the object-side surface of the first lens to the imaging surface will increase, which is not conducive to the thinning of mobile phones, digital cameras and automotive lenses. Therefore, it has always been a goal in the industry to design a multi-element optical imaging lens with good imaging quality, light weight and short si...
