Problems solved by technology

[0003] Traditional miniaturized optical mirrors mounted on portable electronic products mostly use four or five-element lens structures. However, due to the prevalence of high-standard mobile devices, the pixel and imaging quality of optical mirrors are rapidly increasing. , the existing five-piece optical lens group will not be able to meet higher-level photography needs
[0004] Although the six-piece optical lens group has been further developed at present, its refractive power distribution cannot effectively suppress its total length, and its ability to correct aberrations is limited, so it is not enough to be used in portable electronic products that require high imaging quality.

Abstract

An optical imaging lens assembly includes, in order from the object side to the image side, a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element and a sixth lens element. The first lens element with positive refractive power has a convex object-side surface in a paraxial region. The fourth lens element with negative refractive power has a concave object-side surface in a paraxial region. The fifth lens element with positive refractive power has a convex image-side surface in a paraxial region. The sixth lens element with negative refractive power has a concave object-side surface in a paraxial region, a concave image-side surface in a paraxial region and at least one convex shape in the off-axial region of the image-side surface of the sixth lens element. The fifth lens element and the sixth lens element are aspheric lens elements.

Description

technical field [0001] The invention relates to an optical imaging lens group and an image-taking device, in particular to a miniaturized optical imaging lens group and an image-taking device. Background technique [0002] In recent years, with the vigorous development of miniaturized photographic lenses, the demand for miniature imaging modules has increased day by day, and the photosensitive elements of general photographic lenses are nothing more than charge coupled devices (Charge Coupled Device, CCD) or complementary metal oxide semiconductors. There are two types of components (Complementary Metal-Oxide Semiconductor Sensor, CMOS Sensor), and with the improvement of semiconductor process technology, the pixel size of the photosensitive element has been reduced, and today's electronic products are developing with good functions and thin, light and small appearance. Therefore, miniaturized photographic lenses with good imaging quality have become the mainstream in the cu...
