In grinding, the shape errors should be less than the size of the grit in the grinding compound, and in polishing the lap should fit to a few microns. (The better the lap fit, the better the finish.) The laps designed for aspheric surfaces use a combination of small size, small stroke, and compliance to maintain the intimate contact required.
