Abstract: One embodiment of the invention discloses an optical imaging device including an optical lens. The optical lens has N number of lenses, and the N number of lenses are divided into a first lens group and a second lens group and have at least three aspheric lenses. The first lens group is disposed between an object side and an image side, and the first lens group has (N/2)−1 piece of lens. The first lens group includes, in order from the object side, a first lens, a second lens and a third lens, and the second lens is an aspheric lens. The second lens group is disposed between the first lens group and the image side, and an aperture stop is disposed between the first lens group and the second lens group.
