Optical Aspheric Lens
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 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 sometimes cheaper than
the multi-lens design. Aspheric elements are used in the design of
multi-element wide-angle and fast normal lenses to reduce
aberrations.
