Abstract
An optical lens includes a first lens group, a second lens group and an aperture stop disposed between the first lens group and the second lens group. The optical lens satisfies the conditions of 7 mm<D<25 mm and 0.3<D/LT<0.5, where D is a diameter of a lens surface of the second lens group furthest from the first lens group and LT is a total lens length measured along an optical axis between a lens surface of the first lens group furthest from the second lens group and the lens surface of the second lens group furthest from the first lens group.
