single-point diamond-turned mirror performance before and after polishing

the surface finish of a single-point diamond-turned (spdt) mirror produced in 1977 on the large (2-meter swing) excello lathe at the union carbide corporation's y-12 plant in oak ridge, tennessee, was such that it was not possible to do visible alignment using it therefore, it was necessary to polish the mirror by hand. this was done at t..
