Figure 5
Energy resolution, Δλ/λ, for a 600 lines mm−1 grating with included angles fixed at 170 (circles) and 174° (triangles) estimated from the ray-traced spots, together with the defocus (dashed lines) and source-size (dotted lines) limited resolutions. The total of the source-size and aberration (defocus, coma and spherical) limited resolutions is also plotted (solid lines). |
