Optical image capturing lens assembly

Abstract

The present disclosure provides an optical image capturing lens assembly comprising, in order from an object side to an image side: a first lens element with positive refractive power having a convex image-side surface; a second lens element; a third lens element; a fourth lens element, at least one of an object-side surface and an image-side surface thereof being aspheric; a fifth lens element, at least one of an object-side surface and an image-side surface thereof being aspheric; and a sixth lens element with negative refractive power having a concave image-side surface, at least one of an object-side surface and the image-side surface thereof being aspheric, at least one inflection point being formed on at least one of the surfaces thereof. With the aforementioned arrangements, the sensitivity of the optical system can be attenuated while the aberration and astigmatism can be effectively corrected to improve the image quality.

Description

technical field [0001] The invention relates to an optical image pickup lens set, in particular to a miniaturized optical image pickup lens set for electronic products. Background technique [0002] In the process of continuous technological innovation and change, with the rise of mobile phone cameras, the demand for miniaturized photographic lenses is increasing day by day, and the photosensitive element of general photographic lenses is nothing more than a charge coupled device (CCD) or complementary There are two types of metal oxide semiconductor (Complementary Metal-Oxide Semiconductor, CMOS), and due to the advancement of semiconductor process technology, the pixel area of ​​the photosensitive element has been reduced, leading the miniaturization of photographic lenses to gradually develop into the high-pixel field. At the same time, the market for The requirements for image quality are also increasing day by day. [0003] Traditional high-resolution miniaturized phot...

Problems solved by technology

[0003] Traditional high-resolution miniaturized photographic lenses mounted on portable electronic products, as shown in U.S. Patent No. 7,502,181, mostly use a five-element lens structure. However, due to high-end smart phones (Smart Phone) and PDA ( The popularity of high-standard mobile devices such as Personal Digital Assistant has driven the rapid increase in pixel and imaging quality of miniaturized photographic lenses. The existing five-element lens group will not be able to meet higher-end photographic lens modules. Products are constantly developing towards high performance and thinner and thinner. Therefore, there is an urgent need for an image capture lens group that is suitable for thin, light and portable electronic products with good image quality and does not make the total length of the lens too long.
