Abstract

A three-step design procedure is developed for dielectric stacks which are required to be nonpolarizing for a given wavelength λ_r and angle of incidence θ_0,r, at which the reflectance R_r is prescribed. The method leads to solutions in which only three layer materials occur and can be applied for a wide range of values of θ_0,r and R_r. The media can be chosen from the available coating materials. Furthermore, the procedure offers the possibility of optimizing with respect to the behavior of the reflectance in the neighborhood of λ_r and θ_0,r. An example is elaborated, and its results are compared with an actually produced coating.
