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.
Â
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.
