Problems solved by technology

[0003] 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

The invention discloses an optical image capturing system comprising a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens in order from an object side to an image side. At least one of the first lens to the fifth lens has a positive refractive power. The sixth lens may have a negative refractive power and both surfaces thereof are aspherical, wherein at least one surface of the sixth lens has an inflexion point. The lenses with the refractive power in the optical image capturing system are the first lens to the sixth lens. When the specific conditions are met, greater optical reception and better optical path adjustment capability can be achieved to improve the 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 device (Charge Coupled Device; CCD) or a complementary metal oxide semiconductor element (Complementary Metal-Oxide Semiconductor Sensor; CMOS Sensor). With the improvement of the semiconductor manufacturing process, 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 image quality are also increasing. [0003] Traditional optical systems mounted on portable devices mostly use four-element or five-element lens structures. However, du...
