Problems solved by technology

However, the optical system designed with a large aperture often faces the situation of producing more aberrations, resulting in the deterioration of the surrounding imaging quality and the difficulty of manufacturing, while the optical system designed with a wide viewing angle will face an increase in the distortion rate of imaging. The advanced optical imaging system can no longer meet the requirements of more advanced photography

Abstract

The present invention discloses an optical image capturing system, comprising, from an object side to an image side, a first lens with positive refractive power having a convex object-side surface; a second lens with refractive power; a third lens with refractive power; a fourth lens with refractive power; a fifth lens with refractive power; and a sixth lens with negative refractive power having a concave image-side surface, wherein both surfaces of the all lenses are aspheric surfaces, and at least one surface of the sixth lens has an inflection point. In the optical image capturing system, the first to sixth lenses have refractive power. When a specific condition is met, a greater light receiving ability and a better optical path adjusting ability are achieved, so as to improve imaging quality.

Description

technical field [0001] The invention relates to an optical imaging system, 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 a 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), 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- or five-lens lens structures. However, due to ...
