Title:
OPTICAL SYSTEM AND CAMERA MODULE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2023/239159
Kind Code:
A1
Abstract:
An optical system disclosed in an embodiment of the present invention comprises first to eleventh lenses arranged along the optical axis toward a sensor side from an object side, wherein: the first lens has a positive (+) refractive power at the optical axis, and has a meniscus shape of protruding to the object side; the eleventh lens has a negative (-) refractive power at the optical axis, and has a recessed sensor side surface; a sensor side surface of the eleventh lens has a critical point between ends of an effective area at the optical axis; an object side surface and a sensor side surface of the tenth lens are provided without a critical point up to the ends of the effective area of the optical axis; and the object side surface and the sensor side surface of the tenth lens can have an inclined angle of 10 degrees or less that is up to 43% of the effective radius of the tenth lens at the optical axis.
