I) Fresnel lenses are inadequate for any but the most crude applications, but, 

as a matter of fact, in these days of nanotechnology and laser machine tools, would it be possible to produce a fresnel lens as a spiral with millions of grooves, somewhat like an old-style record, but with optical quality. This would be as a flat lens. There would still be color aberration. 

 

II) For those who want to produce F2 or F1 mirrors, the only problem is parabolization, which is very difficult at such ratios. In these days of computerized corrections, what of a CCD which takes the image from a perfect spherical F1 or F2 mirror and corrects for aberration?  Thus, the hard part could perhaps be circumvented. Would this be possible?
