Abstract
A grazing incidence optic is fabricated by grinding, polishing, or both, using a tapered, barrel-shaped tool. The optic surface to be ground or polished is placed in contact with a selected portion of the grinding or polishing surface of the tool, and the tool is rotated about its longitudinal axis. The optic is subjected to a reciprocating grinding movement along the length of the barrel tool. A helical groove in the tool allows slurry to pass between the optic surface being worked and the tool surface. Air is forced between the optic surface and the tool surface to release the optic from the tool.
