BK7/Fused Silica Material 60mm 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.
Aspheric elements are used in the design of multi-element wide-angle and fast normal lenses to reduce aberrations.
While in principle aspheric surfaces can take a wide variety of forms, aspheric lenses are often designed with surfaces of the form
