Abstract

The invention relates to an optical system, an image capturing module and an electronic device. The optical system includes: a first lens having negative refractive power; a second lens having refractive power, wherein the object side surface of the second lens is a convex surface; a third lens having positive refractive power, wherein the image side surface of the third lens is a convex surface; a fourth lens with negative refractive power; a fifth lens with positive refractive power; a sixth lens having positive refractive power, wherein the image side surface of the sixth lens is a convex surface; and a seventh lens having negative refractive power, wherein the object side surface of the seventh lens is a concave surface. The optical system satisfies the following conditions shown in the description, wherein f2 is the effective focal length of the second lens, and f1 is the effective focal length of the first lens. The optical system has the wide-angle characteristic and can meet the requirement of large-range shooting.

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 gradual development of photographic imaging technology, consumers have higher and higher requirements on the photographic performance of electronic equipment. At present, the application rate of the five-element camera lens is high, but it is difficult to meet consumers' demand for high resolution. Compared with the five-element camera lens, the seven-element camera lens can obtain relatively higher resolution and greater design flexibility, so it can be used more in high-end electronic equipment to obtain higher Capture resolution and clarity. On the other hand, due to the development of photography and imaging technology, consumers' demand for various photography is also gradually increasing. In particular, consumers have a high demand for taking group photos, large scenes, etc. There...
