Optical imaging lens and electronic equipment

Abstract

The invention discloses an optical imaging lens, which comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens, wherein the first lens has refractive power, and an image side surface thereof is concave in a paraxial region; the second lens has negative refractive power, and an object side surface thereof is convex in a paraxial region; the third lens has refractive power, an object side surface thereof is convex in a paraxial region, and an image side surface thereof is convex in a paraxial region; the fourth lens has refractive power; the fifth lens has positive refractive power, and an image side surface thereof is convex in a paraxial region; and the six lens has negative refractive power, an image side surface thereof is concave in a paraxial region, and an object side surface has at least one inflexion point. The optical imaging lens can effectively enhance the correction of the chromatic aberration to improve the imaging quality by rationally combining the materials of the lenses, optimally configures a ratio of center thickness to edge thickness of the sixth lens, effectively avoids the problem that a thickness ratio of the sixth lens is too large or too small, avoids difficulty in molding production or poor molding, and can achieve good imaging quality while adopting a large aperture. The invention further discloses electronic equipment.

Description

technical field [0001] The invention relates to the technical field of optical systems, in particular to an optical imaging lens. The invention also relates to an electronic device. Background technique [0002] With the rapid development of science and technology, especially electronic technology, mobile and portable electronic devices have been popularized rapidly, which also promotes the vigorous development of related technologies of image modules applied to electronic devices. Image modules have been used more and more widely, such as in smartphones, tablet computers, driving recorders, and sports cameras, and the trend of thinner and lighter electronic products such as smartphones has also increased the demand for miniaturization of image modules. . With the improvement of semiconductor manufacturing process technology, the pixel size of the photosensitive device has been continuously reduced. Correspondingly, in order to meet the thin and light requirements of the i...

Problems solved by technology

[0003] Traditional optical imaging lenses mostly use four-element and five-element lens structures, but the four-element and five-element lens structures have limitations in terms of refractive power distribution, aberration astigmatism correction, and sensitivity distribution, which cannot further satisfy Higher specification imaging requirements
