An aspheric lens or asphere is a lens whose surface profiles are not portions of a sphere or cylinder. In photography, a lens assembly that includes an aspheric element is often called an aspherical lens. The asphere's more complex surface profile can reduce or eliminate spherical aberration and also reduce other optical aberrations such as astigmatism, compared to a simple lens.
Aspherical - An optical element processed with non-spherical surface(s). There are a couple of different ways to create aspherics; e.g. grinding, press molding, injection molding and hybrid methods, any of which requires high-precision technology. Auto-iris Lens - A lens with an electrically controlled iris.
