| titleOfInvention | Optical system, camera module and electronic device |
| abstract | The invention relates to an optical system, a camera module and an electronic device. The optical system sequentially includes from the object side to the image side: a first lens with a positive refractive power; a second lens with a negative refractive power; a third lens with a refractive power; a fourth lens with a positive refractive power; The fifth lens, the object side and the image side of the fifth lens are both aspherical, and at least one of the object side and the image side of the fifth lens has an inflection point; the optical system includes a light that is arranged on the image side of the first lens The optical system satisfies: 1.0<SD11/tan(HFOV)+SAG11<1.5; SD11 is the maximum effective radius of the object side of the first lens, HFOV is half of the maximum field of view of the optical system, and SAG11 is the first lens The vector height of the side of the object. Satisfying the above relationship enables miniaturization of the head of the optical system. |
