Why use Panasonic aspherical glass lenses?
The most notable benefit of Panasonic aspheric lenses is their ability to correct for spherical aberration which results from using a spherical surface to focus or collimate light. All spherical surfaces suffer from spherical aberration, independent of alignment or manufacturing errors, so a non-spherical, or aspheric surface, is needed to correct for it.
Although various techniques exist to correct aberrations caused by spherical surfaces, none match the imaging performance and flexibility that aspheric lenses provide.
Aspheric lenses allow optical designers to correct aberrations using fewer elements to minimise the overall cost of production, as well as reduce system size. As a result, incorporating aspheric lenses can reduce overall system design costs.
