Problems solved by technology

[0004] Traditional optical systems mounted on portable devices mostly use four-element or five-element lens structures. However, due to the continuous improvement of pixels in portable devices and the demand for large apertures such as low-light and night shooting functions from end consumers, existing The advanced optical imaging system can no longer meet the higher-level photography requirements

Abstract

An optical image capturing system, from an object side to an image side, comprises a first, second, third, fourth, fifth and sixth lens elements. The first through fifth lens elements have refractive power and both of an object-side surface and an image-side surface of the fifth lens elements are aspheric. The sixth lens with negative refractive power may have a concave image-side surface. Both of the image-side surface and the object-side surface of the six lens elements are aspheric and at least one of the two surfaces has inflection points. Each of the six lens elements may have refractive power. When specific conditions are satisfied, the optical image capturing system can have a large aperture value and a better optical path adjusting ability to acquire better imaging quality.

Description

technical field [0001] The invention relates to an optical imaging system, and in particular to a miniaturized optical imaging system 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 a photosensitive coupling element (Charge Coupled Device; CCD) or a complementary metal oxide semiconductor element (Complementary [0003] Metal-OxideSemiconductorSensor; CMOSSensor) two types, and with the improvement of semiconductor manufacturing 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. [0004] Traditional optical systems mounted on portable devices mostly use four-element or five-elemen...
