Figure 2
Reconstructed refractive index of a quartz crystal. Shown are the 1 − δ and β parts for the ordinary (001) (red line) and extraordinary (100) (blue line) orientations of the crystal compared with the SiO2 Center for X-ray Optics database values (green dashed line) (Henke et al., 1993) and with the optical constants from amorphous quartz (black points) (Filatova et al., 1999). The insets show a magnified view of the reconstructed anisotropy in the absorption edge areas. The data are available online (Andrle et al., 2020). |
