Title:
OPTICAL SYSTEM AND CAMERA MODULE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2023/224440
Kind Code:
A1
Abstract:
An optical system disclosed in an embodiment of the present invention comprises first to eleventh lenses arranged along an optical axis in the direction from an object side to a sensor side, wherein: the first lens has a positive (+) refractive power on the optical axis and has a convex object-side surface; the refractive index (n3) of the third lens and the refractive index (n4) of the fourth lens satisfy the mathematical formula of 1 < n3/n4 < 1.5; among the first to eleventh lenses, the number of meniscus-shaped lenses that are convex on the optical axis (OA) toward the object side is four or more; and the sensor-side surface of the eleventh lens is provided without a critical point from the optical axis to the end of the effective area, and a first distance, which is the maximum distance, with respect to the optical axis, to a point where the height to the sensor-side surface is less than 0.1 on a straight line perpendicular to the optical axis, may span more than 20% of the effective radius of the sensor-side surface of the eleventh lens.
