摘要： An optical imaging system includes a first lens, a second lens, a third lens, and a fourth lens sequentially disposed from an object side toward an image side on an optical axis, and a reflecting member disposed closer to the object side, as compared to the first lens, and having a reflecting surface configured to change a path of light to be incident to the first to fourth lenses. The first to fourth lenses are disposed to be spaced apart from each other by a preset distance along the optical axis, and 1.3

摘要： A lens assembly includes a lens having an optical portion and a flange portion at a periphery of the optical portion, a spacer having an incident hole through which light passes, and a lens barrel accommodating the lens and the spacer. The lens includes a first D-cut portion and a second D-cut portion formed on a side surface and another side surface of the flange portion in a state of non-contact with the lens barrel, and circular arc portions connecting the first and second D-cut portions to each other. The spacer includes blocking portions having a shape corresponding to a shape of the first and second D-cut portions, and first curved portions having a shape corresponding to a shape of the circular arc portions on an inner side surface, and transmission portions formed in locations in which the blocking portions and the first curved portions are connected to each other.

摘要： An optical imaging system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens sequentially disposed on an optical axis from an object side toward an image side. A distance from an object-side surface of the first lens to an imaging plane of an image sensor is TTL, an overall focal length of an optical system including the first to sixth lenses is F, and TTL/F≤0.83. An optical axis distance between the second lens and the third lens is D23, an optical axis distance between the third lens and the fourth lens is D34, and 2.2
