Visual representation of Ra (top left corner). Hydrophilic acrylic after ablation using parameters: P = 30 W, v = 3.65 m/s and dx = 36.5 µm + 2 additional scans with parameter set of P = 2.5 W, v = 1.03 m/s and dx = 10.3 µm (A). The same sample after polishing using the following parameters: P = 12 W, v = 1000 mm/s, dx = 5 $\mathsf{\mu }\mathrm{m}$ and ${\mathrm{N}}_{\mathrm{p}}$ = 10 (B); after polishing with: P = 29 W, v = 1000 mm/s, dx = 10 $\mathsf{\mu }\mathrm{m}$ and ${\mathrm{N}}_{\mathrm{p}}$ = 10 (C); and after polishing with P = 29 W, v = 1000 mm/s, dx = 5 $\mathsf{\mu }\mathrm{m}$ and ${\mathrm{N}}_{\mathrm{p}}$ = 10 (D). Sa is a different notation of Ra, notation depends on ISO standard used.
