Optical system, camera module, and mobile terminal

Abstract

A camera module disclosed in an embodiment of the invention includes a lens barrel having a through hole therein; and an optical system disposed in the through hole of the lens barrel and having a plurality of lenses which an optical axis is aligned from an object side toward a sensor side, wherein a sensor-side lens closest to an image sensor among the plurality of lenses includes an object-side surface and a sensor-side surface, the sensor-side lens has a length in a first direction orthogonal to the optical axis longer than a length in a second direction, the sensor-side lens includes an outer protrusion protruding on one side in the second direction, and the sensor-side surface of the sensor-side lens may have an asymmetrical shape in a shape of a lens surface from the optical axis to an end of an effective region in the first direction and a lens surface from the optical axis to an end of an effective region in the second direction.
