Abstract

The success of layered synthetic microstructures (LSM) as reflectance enhancing coatings for mirrors at wavelengths <300 A has prompted a study of their properties when applied to diffraction gratings. In designing the coating, its interference order, usually the first order, must be paired with a suitable diffraction order of the grating. In addition a compromise must be made to reduce the incompatibility caused by the simple Bragg law performance of the grating with the corrected Bragg law performance of the coating.
