An aspheric lens is a lens whose surfaces have a profile that is neither a portion of a sphere nor of a circular cylinder. The asphere's more complex surface profile can eliminate spherical aberration and reduce other optical aberrations compared to a simple lens. A single aspheric lens can often replace a much more complex multi-lens system. The resulting device is smaller and lighter, and possibly cheaper than the multi-lens design.
