Abstract: An optical imaging system includes a first lens having a positive refractive power; a second lens having a concave object-side surface in a paraxial region thereof; a third lens having a positive refractive power; a fourth lens having a negative refractive power; a fifth lens having a refractive power; and a sixth lens having a concave image-side surface in a paraxial region thereof, wherein the first to sixth lenses are sequentially disposed in ascending numerical order along an optical axis of the optical imaging system from an object side of the optical imaging system toward an imaging plane of the optical imaging system, and a conditional expression 0.6?CT1/d2?1.4 is satisfied, where CT1 is a thickness of the first lens along the optical axis, and d2 is an air gap along the optical axis between the second lens and the third lens.

Abstract: A camera module is provided. The camera module includes a lens module that is movably disposed inside the housing; and a case that surrounds at least a portion of the housing, wherein an opening through which light has passed is disposed in the case, and an inner surface of the opening includes an inner surface that is convex toward a center of the opening.

Abstract: A lens assembly is provided. The lens assembly includes a spacer; and a first lens coupled to the spacer, wherein a length of the first lens in a first direction, perpendicular to an optical axis, is greater than a length of the first lens in a second direction, perpendicular to both the optical axis and the first direction, the first lens includes a first side surface which extends in the first direction, the spacer includes a plurality of support portions in contact with the first lens, and a side wall portion that connects the plurality of support portions, and the first side surface of the first lens is disposed to face the side wall portion.

Abstract: A spacer is provided. The spacer includes an opening through which light passes and an internal surface that forms the opening, wherein the internal surface includes a first internal surface having a first curvature portion having a first predetermined curvature and a second internal surface disposed to face the first internal surface in a first direction, perpendicular to an optical axis direction, and having a second curvature portion having a second predetermined curvature, a distance between the first internal surface and the second internal surface is less than a distance between surfaces facing each other in the second direction, intersecting the first direction, and the first curvature portion and the second curvature portion are provided as a pair, corresponding to each other, to form an arc of a circle inscribed on the first internal surface and the second internal surface.

Abstract: A folding-type mobile terminal is provided with a camera that is capable of accurately imaging an object. This is accomplished by mounting the camera such that a viewing direction of the display of the terminal is substantially parallel to a camera imaging direction.
