The use of a topography to evaluate the optics of a lens is especially helpful if the lens is a centre near or centre distance concentric design (near centre aspheric optics tend to be more challenging to evaluate with the topographer, although they are also more forgiving to decentration than concentric designs so this type of evaluation is not as helpful in management for aspheric optics).
The large aspheric lens is designed to give a superior homogeneous light beam over the total beam angle.
