Well, the beauty of the eccentric mirror polishers is that the kinematics of the polishing process make the mirror surface ideally spherical. It is possible to machine optical surfaces but you need subwavelength accuracy i.e. better than 500 nm. ------------------------------------------------------------------------------ Sell apps to millions through the Intel(R) Atom(Tm) Developer Program Be part of this innovative community and reach millions of netbook users worldwide.
