Abstract:
1. A method of producing an optical imaging system, which has a plurality of optical elements, comprising: assembling the imaging system with the optical elements substantially arranged in predefined positions; measuring the imaging system with locally resolving determination of the wave-front in the exit pupil or an surface conjugate therewith belonging to the imaging system, for the locally resolving determination of wavefront errors; selecting at least one surface provided as a correction surface on at least one of the optical elements, the correction surface being selected such that the correction surface is arranged in the surface of the exit pupil or a surface conjugate therewith belonging to the imaging system; calculating at least one of a topography and a refractive index distribution of the at least one surface selected as the correction surface belonging to the optical element, in order to correct the wavefront error; removing the at least one optical element provided with the correction surface from the imaging system; locally resolving processing of the at least one correction surface, in order to produce at least one of the calculated topography and refractive index distribution of the correction surface; and installing the optical element having the processed correction surface in the predefined position for the optical element in the imaging system.
