Alumina Lapping, Honing and Polishing

I need an optical figure or angstrom-level finish on a hard material. Who laps and polishes it?

What it is

Rubbing the workpiece against a flat plate charged with diamond slurry to reach flatness and surface finish measured in wavelengths of light rather than thousandths of an inch. The route to optical transparency in a ceramic.
