  • Patent number: 10578783
    Abstract: An optical grating (8) includes a substrate (9), on the surface (9a) 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 (??) 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.
    Type: Grant
