title: Performance of multilayer coated diffraction gratings in the EUV.
abstract: Performance of multilayer coated diffraction gratings has been evaluated in the extreme UV. The application of multilayer coatings to two blazed gratings has produced a significant enhancement in grating efficiency in the 300-A spectral region in first order.
