    摘要: An optical imaging system includes a first lens, a second lens, a third lens, a fourth lens, and a fifth lens. The first lens has positive refractive power and a convex image-side surface. The second lens has negative refractive power. The third lens has negative refractive power. The fourth lens has negative refractive power and an inflection point formed on an image-side surface thereof. The fifth lens has positive refractive power and a convex image-side surface.

    摘要: A zoom optical system includes a first lens group, a position of which with respect to an imaging plane is adjustable, and including first and second lenses. The zoom optical system also includes a second lens group of which a position with respect to the imaging plane is adjustable and includes third to fifth lenses. The zoom optical system further includes a third lens group including a sixth lens. An object-side surface of the first lens is convex.

    摘要: An optical imaging system includes a first lens having a positive refractive power and a convex object-side surface; a second lens having a negative refractive power, a convex object-side surface, and a concave image-side surface; a third lens having a negative refractive power; a fourth lens having a refractive power; a fifth lens having a negative refractive power; and a sixth lens having a positive refractive power. The first to sixth lenses are sequentially disposed in ascending numerical order from an object side of the optical imaging system toward an imaging plane of the optical imaging system, and are the only lenses having a refractive power in the optical imaging system.
