Optical systems, lens modules and electronics

Abstract

An optical system, lens module and electronic equipment, the optical system sequentially includes from the object side to the image side along the optical axis: the first lens to the sixth lens with refractive power, wherein the first lens has positive refractive power, and the third lens has a positive refractive power. Lenses have negative refractive power. The object side of the first lens to the third lens is convex at the near optical axis, and the image side is concave at the near optical axis; the object side of the fourth lens and the image side of the fifth lens are both convex at the near optical axis. is a convex surface, and the image side of the sixth lens is concave at the near optical axis. The optical system satisfies the relation: 1.7

Description

technical field [0001] The invention belongs to the technical field of optical imaging, and in particular relates to an optical system, a lens module and electronic equipment. Background technique [0002] With the development of the vehicle industry, in recent years, the replacement cycle of electronic equipment has become shorter and shorter, and the shooting function has become more and more powerful, and the market has stricter requirements for a single type of lens. As consumers have diverse requirements for shooting environments, there are more and more types of lenses suitable for different shooting environments. Among them, the telephoto lens can obtain a shallower depth of field due to its longer focal length, so it can better handle the details of distant scenes and achieve the imaging effect of compressing the shooting distance. [0003] However, traditional telephoto lenses often have problems such as large size and low imaging clarity. Contents of the inventi...
