Problems solved by technology

[0003] Traditional high-resolution miniaturized photographic lenses mounted on portable electronic products mostly adopt a five-element lens structure. The popularity of miniaturized camera lenses drives higher requirements for pixel and imaging quality, and the existing five-element lens group will not be able to meet higher-level requirements
[0004] Although the traditional six-chip optical system has been further developed at present, the imaging quality is often sacrificed in order to maintain the miniaturization.

Abstract

A photographing optical lens assembly includes, in order from object side to 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 object-side surface being convex in a paraxial region thereof. The second lens element has positive refractive power. The third and fourth lens elements have refractive power. The fifth lens element with negative refractive power has an image-side surface being concave in a paraxial region thereof. An object-side surface and the image-side surface of the fifth lens element are aspheric. The sixth lens element with refractive power has an image-side surface being concave in a paraxial region thereof. When specific conditions are satisfied, it is easier to miniaturize the photographing optical lens assembly and achieve better image quality in a limited space.

Description

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