An optical imaging system includes a reflector, a first lens element, a second lens element, a third lens element, a fourth lens element, and a fifth lens element from an object side to an image side in order along an optical axis. The first lens element to the fifth lens element each include an object-side surface and an image-side surface. The object-side surface of the second lens element has a convex portion in a vicinity of a periphery of the second lens element, and the image-side surface of the second lens element has a concave portion in a vicinity of the optical axis. The image-side surface of the fourth lens element has a convex portion in a vicinity of the optical axis, and the object-side surface of the fifth lens element has a concave portion in a vicinity of a periphery of the fifth lens element.
An optical imaging system, comprising a reflector, a first lens element, a second lens element, a third lens element, a fourth lens element and a fifth lens element in order along an optical axis from an object side to an image side, wherein the optical axis comprises a first optical axis and a second optical axis not coinciding with the first optical axis, the first optical axis and the second optical axis intersect at an intersection point on a reflective surface of the reflector, and lens elements of the optical imaging system which have refractive powers are only disposed along the second optical axis, wherein the first lens element to the fifth lens element each comprises an object-side surface facing towards the object side and allowing imaging rays to pass through and an image-side surface facing towards the image side and allowing the imaging rays to pass through, and wherein the first lens element is arranged to be a lens element having refracting power in a first order from the reflector to the image side, the second lens element is arranged to be a lens element having refracting power in a second order from the reflector to the image side, the third lens element is arranged to be a lens element having refracting power in a third order from the reflector to the image side, the fourth lens element is arranged to be a lens element having refracting power in a fourth order from the reflector to the image side, and the fifth lens element is arranged to be a lens element having refracting power in a fifth order from the reflector to the image side;
