| High-quality vision with enhanced aberration correction of anterior aspheric optics. |
| The system uses a generalized aspheric optic element placed near the aperture stop of an optical instrument to produce these results. |
| Typically, the designer adds more lens elements or applies small perturbations to spherical shapes using aspheric surfaces. |
| The element can be a separate component, or it can be integrated onto a traditional lens element by the addition of a generalized aspheric surface. |
| In addition, the higher imaging quality provided by the aspheric design allows an improved utilisation of the field of view. |
| Transparent plastics also have come into use, especially as they can be molded into elements with aspheric surfaces. |
