Figure 3.1.8

Axial divergence aberration profiles shown for several levels of axial divergence. Case 1 (of Table 3.1.1[link]) is computed for a source length of 12 mm and a sample and receiving-slit length of 15 mm. The remaining three simulations include are of case 2, where Soller slits limit the axial divergence (R = 217.5 mm).
