Advanced optical designs require shapes and materials that are challenging to finish. As
designs become more intricate, new fabrication tools are needed. We discuss advanced
surface-finishing methods, particularly methods that rely on the magnetorheological finishing
process, a stable polishing technology that enables precision fabrication of flats and spheres
as well as increasingly complex optics, such as aspheres and freeform shapes.
