Abstract (en)
[origin: WO2013127741A1] A diffraction grating (10) is specified, comprising: a substrate (1); a grating area (3) having, in a direction running parallel to the substrate (1), a periodic arrangement of first areas (31) with a first grating material and second areas (32) with a second grating material, wherein the first grating material and the second grating material are solid materials with different indices of refraction; and a reflection-reducing or reflection-increasing layer system (4) having at least two layers (41, 42) with different indices of refraction, wherein the reflection-reducing or reflection-increasing layer system (4) is arranged on one side of the grating area (3) facing away from the substrate (1), and an additional layer system (2) having at least two layers (21, 22) with different indices of refraction is arranged between the substrate (1) and the grating area (3). A method for producing the diffraction grating (10) is also specified.
