Abstract
The present disclosure discloses an optical imaging system including, sequentially from an object side to an image side along an optical axis, a first lens having positive refractive power; a second lens having refractive power; a third lens having negative refractive power; a fourth lens having refractive power with a convex object-side surface and a concave image-side surface; a fifth lens having refractive power; and a sixth lens having negative refractive power. Half of a maximal field-of-view Semi-FOV of the optical imaging system satisfies Semi-FOV<15°. A distance TTL along the optical axis from an object-side surface of the first lens to an imaging plane of the optical imaging system, half of a diagonal length ImgH of an effective pixel area on the imaging plane and an effective focal length f of the optical imaging system satisfy 1.9 mm<TTL*ImgH/f<2.7 mm.
