Claim 0:
1. A method for polishing of a surface of an optical workpiece, comprising:
swiveling or advancing a tool with a curved polishing surface relative to the workpiece, so that a contact portion of the polishing surface of the tool is pressed partially against the workpiece to be polished,
moving the tool over a full diameter of the surface to be polished and through a center of the surface to be polished,
rotating the workpiece,
increasing a rotational speed of the workpiece when the tool is moved towards the center of the surface and decreasing the rotational speed of the workpiece when the tool is moved away from the center, and
rotating the tool at a constant rotational speed which is faster than a maximum rotational speed of the workpiece,
wherein the moving of the tool across the diameter of the surface combined together with the rotating of the workpiece results in the contact portion traversing a spiral polishing path.
