Abstract

The invention relates to an optical system, an image capturing module and an electronic device. The optical system includes, in order from an object side to an image side, a first lens with positive refractive power, a second lens with refractive power, a third lens with negative refractive power, a fourth lens with negative refractive power, a fifth lens with positive refractive power, and a sixth lens with negative refractive power. The object-side surface and the image-side surface of the third lens are concave in the circumferential direction. The object-side surface and the image-side surface of the fifth lens are aspheric; and at least one of the object-side surface and the image-side surface has an inflection point. The optical system satisfies the following conditions: CT1 / SD11 islarger than 0.60 and is less than 1.01; TTL / CT1 is larger than 5.5 and is less than 9.0; the CT1 is the thickness of the first lens on the optical axis, the SD11 is half of the maximum effective aperture of the object side surface of the first lens, and the TTL is the distance from the object side surface of the first lens to the imaging surface of the optical system. According to the optical system, the head of the pick-up lens can be smaller, and the requirement of miniaturization design of electronic equipment is met.

Description

technical field [0001] The invention relates to the field of imaging, in particular to an optical system, an imaging module and electronic equipment. Background technique [0002] With the continuous development of electronic devices such as smart phones and tablet computers, the camera function has become an indispensable function in electronic devices, and the volume of electronic devices is increasingly inclined to miniaturization, which also puts forward requirements on the size of the optical system in electronic devices. higher requirements. However, the head of the current camera lens is usually relatively large, which is difficult to meet the requirements of miniaturization design of electronic equipment. Contents of the invention [0003] Based on this, it is necessary to provide an optical system, an imaging module and an electronic device for the problem that the head of the camera lens is relatively large and it is difficult to meet the requirements of the min...
