Abstract

An optical system, a camera module and an electronic device, the optical system sequentially comprising from an object side to an image side along an optical axis: first to sixth lenses having refractive power, the first lens having negative refractive power, the third lens and the sixth lens having positive refractive power, the image side surface of the first lens and the image side surface of the second lens are concave surfaces in a paraxial region, and the object side surface of the second lens, the object side surface and the image side surface of the third lens, the image side surface of the fourth lens, the image side surface of the fifth lens and the object side surface of the sixth lens are convex surfaces in a paraxial region. Through reasonable design of the surface type and the refractive power of each lens of the optical system, the characteristics of large field angle, miniaturization and large aperture can be satisfied.

Description

Technical field [0001] The present invention is an optical imaging technology field, especially involving an optical system, camera module and electronic equipment. Background technique [0002] In recent years, carrying electronic products with photography functions has shown a tendency to become more and more thinner. Therefore, the demand for high imaging quality and miniaturization of optical systems has become higher and higher. There is enough light in the distortion and dim environment. However, the needs of cameras in different environments usually means that the structure of optical systems is more complicated, which ultimately leads to the increase in size and total length of the camera module, which is difficult to apply to light and light electronic products. [0003] Therefore, how to achieve miniaturization and large aperture in the premise of ensuring the optical system with a large viewing angle, it has become one of the issues that must be solved in the industry....
