This lens is made of curve shape, not sphere. The aspherical lens has surface, shown in parabolic surface and polynomial expression. Ellipsoid, hyperboloid, fourth curved surface are examples,Aspherical lenses are designed to reduce spherical aberration
aspheres, are available molded, CNC-polished, or MRF-polished, either with or without anti-reflection (AR) coatings. Aspheres are often employed to collimate light exiting a fiber or laser diode. The surface of an asphere is designed to eliminate spherical aberration.
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, We could provide plano convex aspheric lens, plano concave aspheric lens, double convex(biconvex)aspheric lens
