Figure 4
Representative scattering profiles for three classes of material, inorganics, polymers and metals. The top row [panels (a)–(c)] shows experimental data in absolute units of cm−1, while the bottom row [panels (d)–(f)] shows I multiplied by the typical thickness tD (in centimetres) required for a device of the given material. For reference, the scattering from a Hellma cell (orange + symbols) is also included. The window materials (and thicknesses) considered are quartz (0.44 mm), fused silica (1.1 mm), soda lime glass (1.1 mm), borosilicate glass (0.14 mm), steel (0.1 mm) (Shin et al., 2010), nickel (10 µm × 2) (Yoo et al., 1982), aluminium (1 mm) and vanadium (1 mm) (Imae et al., 2011), shown as a horizontal line. |
