WebThe benefits of aspheric lenses are numerous: They allow for a reduction in spherical aberrations and are ideal for focusing or collimating light, as they can achieve a low ƒ-number. Aspheres also allow the same or better performance using fewer lenses, which often translates to a reduction in both size and weight in a system.
