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 22):
The optical arrangement as claimed in  claim 20 , wherein the incident radiation is incident on the optical grating at at least one angle of incidence (\u03b1) in an angle of incidence range (\u0394\u03b1) between 70\u00b0 and 90\u00b0.
