OPTICAL IMAGING SYSTEM, IMAGE CAPTURE MODULE AND ELECTRONIC DEVICE

WIPO Patent Application WO/2022/052050

A1

Provided are an optical imaging system, an image capture module and an electronic device. The optical imaging system sequentially comprises, from an object side to an image side, a first lens having a positive refractive power, an object-side face of the first lens being a convex surface at an optical axis; a second lens having a refractive power; a third lens having a refractive power; a fourth lens having a positive refractive power, an image-side face of the fourth lens being a convex surface at an optical axis; a fifth lens having a refractive power; and a sixth lens having a refractive power, an object-side face of the sixth lens being a convex surface at an optical axis, and an image-side face of the sixth lens being a concave surface at the optical axis. The optical imaging system satisfies: 0.5
