A simple straightforward design algorithm based on the tuning iteration search is applied to design universal visible antireflection coatings for substrates with indices in the range of 1.45 to 1.784. The method uses a two-material multilayer system starting with a binary code of alternating high and low indices and with all sublayers initially set at equal physical thickness. The thicknesses of all layers are subsequently tuned one by one and one at a time to improve the average reflectivity over the visible spectral region until the antireflection performance stabilizes. It is found that the 30-layer tuning iteration designs for visible antireflection coating for a set of eight different substrates with indices 1.45, 1.50, 1.55, 1.60, 1.65, 1.70, 1.75 and 1.784 lead the final designs to 10–12 layer structures and the average visible spectral reflectivities for the substrates are reduced to approximately 0.173–0.190%.
