Optical components and their methods of manufacture are provided, including a first stack of layers configured to exhibit a first stop band for s-polarized radiation and a second stop band for p-polarized radiation incident on the first stack of layers at an oblique angle, a second stack of layers configured to exhibit a third stop band for s-polarized radiation and a fourth stop band for p-polarized radiation incident on the second stack of layers at the oblique angle, where the cut-on wavelength for the first stop band is approximately equal to or larger than the cut-off wavelength for the third stop band. Optical components are further provided to include extended blocking functionality, and to permit stress balancing in thin-film coatings on opposite sides of a substrate.
