Abstract:
An optical grating ( 8 ) includes a substrate ( 9 ), on the surface ( 9 a ) of which a periodic structure ( 10 ) is formed that is embodied to diffract incident radiation ( 11 ), in particular incident EUV radiation, with a specified wavelength (λ τ ) into a predetermined order of diffraction, in particular into the first order of diffraction (m=+ 1 ). The optical grating also has a coating ( 12 ) applied onto the periodic structure with at least one layer ( 13, 14 ) that is embodied to suppress the diffraction of the incident radiation into at least one higher order of diffraction (m=+ 2 , . . . ) than the predetermined order of diffraction.

Claim (Index 15):
The optical grating as claimed in  claim 14 , wherein the coating has a total reflection layer made of Ru, Zr, Pd, Nb, Mo, or alloys, carbides, nitrides, oxides, borides, or silicides thereof, or C, and an absorber layer, applied to the layer of total internal reflection, made of Si, SiC, Si 3 N 4 , SiO, or SiO 2 .
