Title:
OPTICAL SYSTEM AND CAMERA MODULE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2023/239161
Kind Code:
A1
Abstract:
An optical system disclosed in an embodiment of the invention may comprise first to ninth lenses arranged along an optical axis in the direction from an object side to a sensor side, wherein: the first lens has positive (+) refractive power on the optical axis and has a meniscus shape convex toward the object side; the second lens has positive refractive power on the optical axis and both surfaces of the second lens have a convex shape; the ninth lens has negative (-) refractive power on the optical axis and has a meniscus shape convex toward the object side; the lens having the greatest absolute value of the focal length among the first to ninth lenses is the fourth lens; the lens surface having the greatest absolute value of the radius of curvature among the first to ninth lenses is the object-side surface of the sixth lens; the focal length of the first lens is F1; the focal length of the ninth lens is F9; and mathematical expression -0.5 < F9/F1 < 0 is satisfied.
