| 发明名称 | Refractive beam shaper | ||
| 摘要 | A refractive beam shaper that includes multiple meniscus lenses arranged along their optical axes. Each meniscus lens has a concavely curved surface for entry or exit of a light beam and a convexly curved surface for exit or entry of the light beam. Both surfaces have curvatures such that a collimated light beam entering the respective meniscus lens parallel to an optical axis thereof exits again, as a collimated light beam, with a diameter that is altered compared with the entering light beam. To prevent aberrations, at least one of the two surfaces of each meniscus lens has a predetermined aspherical shape. | ||
