Title:
OPTICAL SYSTEM AND CAMERA MODULE INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2023/224444
Kind Code:
A1
Abstract:
An optical system disclosed in an embodiment of the present invention includes first to eighth lenses arranged along an optical axis in a direction from the object side to the sensor side, wherein: the first lens has a positive (+) refractive power on the optical axis and has a meniscus shape convex toward the object side; the eighth lens has a negative (-) refractive power on the optical axis and has a meniscus shape convex toward the object side; the object side surface of the seventh lens has a critical point; and the sensor side surface of the eighth lens has a critical point, and when an effective diameter of the sensor side surface of the third lens is CA_L3S2, an effective diameter of the object side surface of the fourth lens is CA_L4S1, a maximum thickness among the center thicknesses of the first to eighth lenses is CT_Max, and a maximum gap among the gaps between the first to eighth lenses is CG_Max, the following mathematical relations are satisfied: 0.5 < CA_L3S2 / CA_L4S1 < 1.5, and 0 < CT_Max / CG_Max < 1.
