Surface Finishing of Complex Optics

Aric B. Shorey, Don Golini and William Kordonski

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.
