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 lens element has refractive power, and an object-side surface of the first lens element is aspheric. The second 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 object-side surface. The image-side surface and the object-side surface of the sixth lens element are aspheric and at least one of the two surfaces has inflection points. The second through fifth lens elements have refractive power. When specific conditions are satisfied, the optical image capturing system can have a large aperture value and a lower height of the optical image capturing system, and it can also improve imaging quality.

Description

technical field [0001] The present invention relates to an optical imaging system, more specifically, 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 two types of photosensitive coupling device (Charge Coupled Device; CCD) or complementary metal oxide semiconductor element (Complementary Metal-Oxide Semiconductor Sensor; CMOS Sensor), and with the advancement of semiconductor manufacturing technology, the pixel of the photosensitive element The size is shrinking, and the optical system is gradually developing into the high-pixel field, so the requirements for imaging quality are also increasing. [0003] Traditional optical systems mounted on portable devices mostly use four-element or five-element...
