| description | PCT No. PCT/EP93/02577 Sec. 371 Date Apr. 28, 1995 Sec. 102(e) Date Apr. 28, 1995 PCT Filed Sep. 23, 1993 PCT Pub. No. WO94/07422 PCT Pub. Date Apr. 14, 1994In order to render possible the ablation to different depths in a process for correcting the shape of a lens in which the surface of the lens is acted upon by the radiation of a pulsed radiation source through a shutter in specific regions exposed by the shutter and thereby removing material from the lens by the radiation effect during the impingement of each radiation pulse, wherein the radiation is concentrated in a bundle of rays, the cross section of which is smaller when striking the lens surface than that of the lens surface exposed by the shutter, and wherein the bundle of rays is moved such that the entire lens surface exposed by the shutter is irradiated by radiation pulses consecutively impinging on the lens surface, it is suggested that the bundle of rays is moved between successive radiation pulses only to such an extent that the regions of the lens surface struck by the radiation pulses consecutively impinging on the lens surface partially overlap. A device is also suggested for performing this process. |
