Abstract: A lens module includes a lens barrel; a lens accommodated in the lens barrel; and a coupling member coupled to the lens barrel, disposed on one side of the lens to fix the lens to the lens barrel. A width of the lens in a first direction perpendicular to an optical axis is smaller than a width of the lens in a second direction perpendicular to the optical axis and intersecting the first direction. The lens barrel is disposed to at least partially expose the coupling member in the first direction and to at least partially overlap the coupling member in the second direction.

Abstract: An optical imaging system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens sequentially arranged along an optical axis from an object side toward an image side. The fifth lens has a positive refractive power, a focal length of the fifth lens is smaller than an overall focal length of the optical imaging system, and −0.38≤R10/f≤−0.32, where R10 is a radius of curvature of an image-side surface of the fifth lens and f is the overall focal length of the optical imaging system.

Abstract: A lens assembly includes a lens including an optical portion to refract light and a flange portion extended along a periphery of at least a portion of the optical portion, and a lens barrel to accommodate the lens. The flange portion has a non-circular shape and includes a first di-cut portion on a first side surface of the flange portion, a second di-cut portion on a second side surface of the flange portion, and arc portions connecting the first di-cut portion and the second di-cut portion. A first distance between the first di-cut portion and an optical axis of the lens and a second distance between the second di-cut portion and the optical axis of the lens are smaller than a distance between respective opposite ends of the arc portions and the optical axis.
