Title:
OPTICAL IMAGING SYSTEM AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/003720
Kind Code:
A1
Abstract:
An optical imaging system and an electronic device. The optical imaging system (100) sequentially comprises from an object side to an image side: a first lens (101) having negative refractive power and a convex object side surface and a concave image side surface; a second lens (102) having positive refractive power and a convex object side surface and a concave image side surface; a third lens (103) having positive refractive power and a convex object side surface; a fourth lens (104) having positive refractive power and a convex object side surface and a convex image side surface; a fifth lens (105) having positive refractive power and a concave object side surface and a convex image side surface; a sixth lens (106) having positive refractive power and a convex image side surface; and a seventh lens (107) having negative refractive power and a concave image side surface. The optical imaging system and the electronic device are highly miniaturized, lightweight, and provide good imaging quality.
