OPTICAL SYSTEM, IMAGE CAPTURING MODULE AND ELECTRONIC DEVICE

WIPO Patent Application WO/2021/026869

A1

An optical system (100), sequentially comprising from an object side to an image side: a first lens (L1) having positive refractive power, an object-side surface (S1) of the first lens (L1) being a convex surface at the circumference; a second lens (L2), a third lens (L3), a fourth lens (L4), a fifth lens (L5), a sixth lens (L6), and a seventh lens (L7) having refractive power; and an eighth lens (L8) having negative refractive power. An image-side surface (S14) of the seventh lens (L7) is a concave surface at the optical axis. In addition, the optical system (100) satisfies 1
