Problems solved by technology

[0003] Traditionally, optical systems mounted on electronic products mostly use four-element or five-element lens structures. However, due to the prevalence of high-standard mobile devices such as smart phones (Smart Phone) and tablet computers (Tablet PC), the optical system is driven by the pixel With the rapid increase in imaging quality, known optical systems will not be able to meet higher-level photographic systems
[0004] In recent years, electronic products are becoming thinner and lighter, so the corresponding imaging device needs to be miniaturized ac

Abstract

The invention discloses an optical lens, an image capturing apparatus and an electronic apparatus. The optical lens includes 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. The first lens has negative refractive power, and the portion, near an optical axis, of the surface of an image side of the first lens is a concave surface. The second lens has refractive power. The third lens has positive refractive power. The fourth lens has positive refractive power, and the portion, near the optical axis, of the surface of an image side of the fourth lens is a convex surface. The both surfaces of the fourth lens are aspherical. The fifth lens has negative refractive power, and the portion, near the optical axis, of the surface of an image side of the fifth lens is a concave surface. The portion, away from the optical axis, of the surface of an image side of the fifth lens includes at least one convex surface. The both surfaces of the fifth lens are aspherical. The sixth lens has refractive power, and the portion, near the optical axis, of the surface of an image side of the sixth lens is a concave surface. The portion, away from the optical axis, of the surface of an image side of the sixth lens includes at least one convex surface. The both surfaces of the sixth lens are aspherical. When a specific condition is satisfied, the sensitivity of the optical lens is lowered, and a visual angle of the optical lens is enlarged.

Description

technical field [0001] The present invention relates to an optical lens and an image-taking device, and in particular to a miniaturized optical lens and an image-taking 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, optical systems mounted on electronic products mostly use fo...
