Abstract

The invention discloses an optical imaging system and an electronic device. The optical imaging system includes a first lens with positive refractive power, a second lens with negative refractive power, a third lens with refractive power, a fourth lens with positive refractive power, and a fifth lens with negative refractive power, in order from the object side to the image side, wherein the object side surface of the first lens is a convex surface; the image side surface of the second lens is a concave surface at the circumference; the object side surface of the third lens is a concave surface at the circumference, and the image side surface of the third lens is a convex surface at the circumference; the object side surface of the fourth lens is a convex surface; and at least one of the object side surface and the image side surface of the fifth lens includes at least one inflexion point. The optical imaging system also includes an infrared optical filter which is arranged between theobject side surface of the first lens and the image side surface of the fifth lens. Through adjusting of the position of the infrared optical filter and reasonable matching of the five lenses, the optical imaging system can satisfy the high pixel demand and can realize ultra-thinning at the same time.

Description

technical field [0001] The invention relates to optical imaging technology, in particular to an optical imaging system and an electronic device. Background technique [0002] Electronic devices such as smart phones and tablets are generally equipped with an optical imaging system to realize the camera function. With the development of science and technology, people have higher and higher requirements for taking pictures, and optical imaging systems with high pixels are more favored by people. The current conventional method is to increase the number of pixels by increasing the number of lenses, but the increase in the number of lenses will inevitably increase the height of the module, which is not conducive to the ultra-thinning of electronic devices. Contents of the invention [0003] Embodiments of the present invention provide an optical imaging system and an electronic device. [0004] The optical imaging system according to the embodiment of the present invention in...
