Abstract
An optical imaging system sequentially includes a first lens, a second lens, a third lens, a fourth lens and a fifth lens from an object side to an image side along an optical axis. The first lens has positive refractive power, with an object-side surface being convex at the optical axis; the second lens has refractive power, with an image-side surface being convex at the optical axis; the third lens has refractive power; the fourth lens has positive refractive power, with an image-side surface being convex at the optical axis; the fifth lens has negative refractive power, with an object-side surface being convex at the optical axis and an image-side surface being concave at the optical axis; a diaphragm is arranged between the object side of the optical imaging system and the fifth lens.
