Abstract
The present disclosure discloses an optical imaging system, comprising, sequentially along an optical axis from an object side to an image side, a prism, a diaphragm, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens, where each of the first lens to the seventh lens has a refractive powers. The prism reflects light incident to the prism along a first direction, to cause the light to emerge from the prism along a second direction. The diaphragm to the seventh lens are sequentially disposed from the prism to the image side along the second direction. The second lens has a positive refractive power, and an image-side surface of the second lens is a concave surface. The third lens has a negative refractive power. The fourth lens has a negative refractive power, and an image-side surface of the fourth lens is a concave surface. The fifth lens has a positive refractive power. At least one of surfaces from an object-side surface of the first lens to an image-side surface of the seventh lens is an aspheric surface.
