    Abstract: An optical system includes: a first lens having refractive power; a second lens having refractive power; a third lens having refractive power and comprising an image-side surface which is convex in a paraxial region; a fourth lens having refractive power; a fifth lens having refractive power and comprising an image-side surface which is concave in the paraxial region; a sixth lens having refractive power; and a stop disposed in front of an object-side surface of the first lens. The first to sixth lenses are sequentially disposed from an object side. A radius of the stop SD and an overall focal length of the optical system f satisfy: 0.2

    Abstract: An optical imaging system includes a first lens group having a first group of lenses. A foremost lens of the first group of lenses is a lens closest to an object side and has a positive refractive power. The optical imaging system also includes a second lens group having a second group of lenses. A rearmost lens of the second group of lenses is a lens closest to an imaging plane and has convex surfaces. The first and second lens groups are sequentially disposed from the object side to an imaging plane. An expression TL/f1

    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: An optical imaging system includes a first lens having positive refractive power, a second lens, a third lens, a fourth lens, and a fifth lens, arranged in order from an object side. The first lens is shaped such that a length of a first axis, which intersects an optical axis, is greater than a length of a second axis, which intersects the optical axis and is perpendicular to the first axis. The optical imaging system satisfies 4.5

    Abstract: An optical imaging system includes: a first lens group including a plurality of lenses; a second lens group including a plurality of lenses; a first reflecting member disposed on an object side of the first lens group; and a plurality of second reflecting members arranged between the second lens group and an image sensor. One or both of the first lens group and the second lens group is movable along an optical axis, an interval along the optical axis between the first lens group and the second lens group is varied between a first interval and a second interval smaller than the first interval, and as at least one of the first lens group and the second lens group is moved, one or more of the second reflecting members are moved.
