Title:
OPTICAL SYSTEM AND CAMERA MODULE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2023/224452
Kind Code:
A1
Abstract:
An optical system disclosed in embodiments includes first to ninth lenses arranged along an optical axis in a direction from the object side to the sensor side, wherein the first lens and the third lens have different refractive powers on the optical axis, the first lens to the third lens have meniscus shapes convex on the optical axis toward the object side, and the object-side surfaces of the respective eighth and ninth lenses have convex shapes on the optical axis, and the following relations may be satisfied: 0.5 <∑CT / ∑CG < 3 and 0 < CT_MAX / CG_MAX < 2, where ∑CT is the sum of the center thicknesses of the first to ninth lenses, ∑CG is the sum of the gaps between the first to ninth lenses along the optical axis, CT_MAX is the maximum of the center thicknesses of the lenses; and CG_MAX is the maximum of the gaps along the optical axis.
