WebNov 1, 2024 · The linear errors of the 2D grating system are better than +50 nm and −40 nm in the X-direction and +100 nm and −80 nm in the Y-direction. The difference is due to the difference between the dual gratings used in test 3, so a 2D grating with as large an area as possible should be used. Web1-2. The Grating Equations. As shown in Fig.1-1 and Fig.1-2, α is the angle between the incident light and the normal to the grating (the incident angle) and ß is the angle between the diffracted light and the normal to the grating (the diffraction angle), then, they satisfy the following relationship: as shown in Fig.1-1, in case of transmission grating
