Abstract

The invention discloses an imaging-used optical system, an image capturing device and an electronic device. The imaging-used optical system sequentially comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens sequentially from an object side to an image side, wherein the first lens has positive refractive power, and the surface, close to the optical axis, of the object side is a convex surface; the surface, close to the optical axis, of the image side of the third lens is a concave surface; the surface, close to the optical axis, of the image side of the fourth lens is a concave surface; the fifth lens has positive refractive power; and the sixth lens has negative refractive power, the surface, close to the optical axis, of the image side is a concave surface, the off-axis place on the surface of the image side contains at least one convex surface, and both the object side surface and the image side surface are aspheric surfaces. When specific conditions are met, the miniaturization of the imaging-used optical system can be maintained, and the feature of a short total length when configuration requirements of a large aperture and a large viewing angle are considered. The invention also discloses an image capturing device comprising the above imaging optical system and an electronic device with the image capturing device.

Description

technical field [0001] The present invention relates to an imaging optical system and an image pickup device, and in particular to a miniaturized imaging optical system and an image pickup device applied to an electronic device. Background technique [0002] In recent years, with the rise of electronic products with photographic 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 device (Complementary Metal-Oxide Semiconductor Sensor, CMOS Sensor), and with the improvement of semiconductor process technology, making The pixel size of the photosensitive element is shrinking, and the optical system is gradually developing into the high-pixel field, so the requirements for image quality are also increasing. [0003] Traditionally, the optical systems mounted on electroni...
