Document Type and Number:
WIPO Patent Application WO/2022/052018
Kind Code:
A1
Abstract:
An optical system (100), a camera module (200), and an electronic device (30). The optical system (100) comprises a first lens (L1), a second lens (L2), a third lens (L3), a fourth lens (L4), a fifth lens (L5), a sixth lens (L6), a seventh lens (L7), and an eighth lens (L8) that are sequentially arranged from an object side to an image side along the direction of an optical axis; the first lens (L1) has positive refractive power, the object side surface (S1) of the first lens (L1) is a convex surface at the optical axis, and the image side surface (S2) of the first lens (L1) is a concave surface at the optical axis; the second lens (L2) has negative refractive power, the object side surface (S3) of the second lens (L2) is a convex surface at the optical axis, and the image side surface (S4) of the second lens (L2) is a concave surface at the optical axis; the eighth lens (L8) has negative refractive power, and the object side surface (S15) of the eighth lens (L8) is a concave surface at the optical axis; and the optical system (100) satisfies the following relation expression: |f12/f78|<2.
