The impact of beam size for correction of an analytical input surface (top), comprising a low-frequency parabolic component with a period of ∼100 mm and a medium-frequency sinusoidal component with a period of ∼3 mm. The 10 mm and 5 mm beams are effective at correcting the low-frequency errors with a short total dwell time. However, they cannot correct the medium-frequency errors, which remain visible in the residual surface post-figuring. The 1 mm beam effectively corrects both the low-frequency and the medium-frequency errors, yielding a residual surface with greatly improved r.m.s. and PV errors. However, the required dwell time is much longer than for the larger beam sizes.
