Problems solved by technology

[0003] The traditional optical systems mounted on portable electronic products mostly use four or five lens structures, but due to the prevalence of high-standard mobile devices such as Smart Phones and Tablet PCs, the optical With the rapid increase in pixels and imaging quality of the system, known optical systems will not be able to meet higher-level photography systems
[0004] Although the six-element optical system has been further developed at present, due to the insufficient refractive power and surface symmetry of the first lens and the sixth lens, the effect of correcting various aberrations of the optical system cannot be effectively exerted, thereby affecting the imaging quality. At the same time, due to the poor ability to shorten the total length of the optical system, its application in miniaturized electronic devices is limited

Abstract

An image capturing lens assembly includes, in order from an object side to an 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 an object-side surface being convex in a paraxial region thereof. The second lens element has negative refractive power. The third lens element has refractive power. The fourth lens element has refractive power. The fifth lens element with refractive power has two surfaces being both aspheric, wherein at least one of the surfaces of the fifth lens element has at least one inflection point thereon. The sixth lens element with positive refractive power has an image-side surface being convex in a paraxial region thereof, wherein the surfaces of the sixth lens element are both aspheric.

Description

technical field [0001] The present invention relates to an image capture system lens group, and in particular to a miniaturized image capture system lens group applied to electronic products. Background technique [0002] In recent years, with the rise of portable electronic products with photography functions, the demand for optical systems has increased day by day. The photosensitive element of the general optical system is nothing more than two types of photosensitive coupling device (Charge Coupled Device, CCD) or complementary metal oxide semiconductor device (Complementary Metal-Oxide Semiconductor Sensor, CMOS Sensor), and with the improvement of semiconductor process technology, The pixel size of the photosensitive element is reduced, and the optical system is gradually developing into the high-pixel field, so the requirements for imaging quality are also increasing. [0003] The traditional optical systems mounted on portable electronic products mostly use four or ...
