Abstract
We discuss the production of antireflection coating with low reflection zones in the spectral regions around the wavelengths of 546nm, 1060 nm and 11000 nm and additional demands for the reflectance maxima in the visible spectral region. For the coating production we use ZnSe as a substrate material and ZnS/YbF3 as layer materials. Their optical parameters are accurately determined in a wide spectral region using modern characterization and reverse engineering software tools. For the coating production we apply broad band monitoring in the spectral region from 1200 to 2300 nm that does not overlap with the regions where target requirements are specified. In order to select the most practical design that can be reliably manufactured we apply a combination of various modern design approaches and computational manufacturing experiments simulating production runs. Application of the most up-to-date software tools allows us to obtain excellent manufacturing results even from the first production run.
