Five-piece high-pixel optical imaging lens

Abstract

The invention relates to a five-piece type high-pixel optical imaging lens which sequentially comprises a diaphragm, a first lens, a second lens, a third lens, a fourth lens, a fifth lens and an optical filter from an object side to an image side, and the five-piece type high-pixel optical imaging lens meets the following relational expression: ImgH / f is greater than 0.8; 0.2 < = CT1 / sigma CT < = 0.35; wherein f is the focal length of the imaging lens group, ImgH is half of the length of a diagonal line of an effective imaging area of the imaging lens group, CT1 is the thickness of the first lens on the optical axis, and sigma CT is the sum of the thicknesses of all the lenses on the optical axis. According to the optical imaging lens, the five-piece type lens combination is adopted, low-cost manufacturing is effectively guaranteed, through reasonable refraction power matching, it is guaranteed that the optical imaging lens has the good light converging capacity, the imaging quality is effectively improved, meanwhile, the optical imaging lens has the short optical system total length, the overall size of the lens is effectively reduced, and therefore the lens is more suitable for a miniaturized electronic device.

Description

technical field [0001] The invention relates to the technical field of optical lenses, in particular to a five-piece high-pixel optical imaging lens. Background technique [0002] With the rapid development of science and technology, especially electronic technology, mobile and portable electronic devices have been rapidly popularized, which promotes the vigorous development of related technologies of optical imaging lenses applied to electronic devices. Optical imaging lenses are constantly evolving, and their applications are more extensive, such as smartphones, tablet computers, driving recorders, and sports cameras. The continuous upgrading trend of smart phones and other electronic products also makes people have more and more requirements for lenses. higher. [0003] 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...

Problems solved by technology

However, as the number of optical lenses increases, the distance from the object-side surface of the first lens to the imaging surface on the optical axis will increase, which is not conducive to the thinning of mobile phone, digital camera and automotive lenses, and the existing six-piece optical lens High manufacturing cost is not conducive to enterprises to improve market competitiveness
