Such an unusual optical behavior as described is possible by carefully designing higher-order aberrations, an art that companies develop over decades, and for which aspheres now offer new and extremely valuable possibilities. To achieve the quality specifications, the designer must control simultaneously many system aberrations. Aberrations can be defined as geometrical ray intersections, and their standard classification in terms of astigmatism, coma, and spherical aberration can be found in any textbook.
Several parameters define the quality of the subaperture polishing process: mechanical stability, and the constantness of the polishing slurry and tool wear. To overcome the intrinsic limitations of such a chemo-mechanical removal process, alternative technologies for controlled material removing have been studied, including fluid jet polishing, ion beam figuring, and magnetorheological finishing. Common to these new technologies, which are based on fluids or ion beams, is the minimization of tool wear.
The shaping tool allows permanent refiguring and is moved in an adapted polar coordinate system, which provides higher accuracy when compared to copying a simple template. 3 Principle of a copy machine for aspheres. The introduction of the computer around 1976 revolutionized optical fabrication. The technical possibility of continuous path control by computer initiated modern generating and polishing methods. With regard to generating, two approaches were chosen by the scientists and engineers at that time.
