Abstract

The present invention discloses an optical imaging system, an image-taking device, and an electronic device. The optical imaging system orderly comprises a first lens having refractive power, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens from an object side to an image side. The first lens has positive refractive power, and the object side surface of the first lens is a convex surface near an optical axis. The second lens has refractive power. The third lens has positive refractive power. The fourth lens has refractive power. The fifth lens has refractive power, the image side surface is a concave surface near the optical axis, and the object side surface and image side surface are aspheric surfaces. The sixth lens has refractive power, the image side surface is a concave surface near the optical axis, and the object side surface and the image side surface are aspheric surfaces. The first lens, the second lens, the third lens, the fourth lens, the fifth lens and the sixth lens have no relative movement in the optical axis. The optical imaging system also comprises an aperture arranged between an imaged object and the third lens.

Description

technical field [0001] The invention relates to an optical photography system, an image pickup device and an electronic device, in particular to an optical photography system and an image pickup device suitable for the electronic device. Background technique [0002] In recent years, with the vigorous development of miniaturized photographic lenses, the demand for miniature imaging modules has increased day by day, and the photosensitive elements of general photographic lenses are nothing more than photocoupled devices (ChargeCoupledDevice, CCD) or complementary metal oxide semiconductor elements (ComplementaryMetal -OxideSemiconductorSensor, CMOSSensor) two types, and with the improvement of semiconductor process technology, the pixel size of the photosensitive element is reduced, coupled with the development trend of today's electronic products with good functions and thin, light and small appearance, so it has good image quality The miniaturized photographic lens has beco...
