MULTIFOCAL LENS WITH A DIFFRACTIVE OPTICAL POWER REGION |
| 摘要 |
A lens system is presented having a diffractive optical power region. The diffractive optical power region has a plurality of concentric surface relief diffractive structures. A greater portion of light incident on a diffractive structure near the center point contributes to the optical power than light incident on a diffractive structure peripherally spaced therefrom.
