Abstract

The embodiment of the invention discloses an optical system, a camera module and an electronic device. The optical system sequentially comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens from an object side to an image side along an optical axis. The optical system satisfies the following conditional expressions: 0.6 mm<-1><FNO / Imgh < 1.2 mm<-1>; wherein FNO is the number of apertures of the optical system, and Imgh is half of the image height corresponding to the maximum field angle of the optical system. According to the embodiment of the invention, through the reasonable combination design of the refractive power and the surface type of the six lenses, the provided optical system can meet the characteristics of a large image surface, can obtain enough light flux, guarantees the imaging performance, and facilitates the meeting of the requirements of high-resolution imaging.

Description

technical field [0001] The present application relates to the technical field of optical systems, in particular to an optical system, a camera module and electronic equipment. Background technique [0002] In recent years, with the continuous development of science and technology, electronic devices such as smartphones, tablet computers, and drones have gradually become an indispensable part of daily life, and people have higher and higher requirements for these electronic devices. For example, in the related art, due to the low imaging resolution of the imaging lens mounted on the electronic device, it can no longer meet the needs of people. Contents of the invention [0003] This application provides an optical system, camera module and electronic equipment. Through the reasonable combination design of six lens refractive power and surface shape, the provided lens can meet the needs of larger wide-angle shooting at the same time, and has a higher imaging pixel character...
