Calculator

The calculator performs crystallographic calculations (Fig. 1). When entering either [u,v,w] or (h,k,l), the indices must be separated by commas. [] or () are automatically added. Figures 2 and 3 show results for [uvw] and (hkl) indices.

Figure3

Figure 3 (hkl)1, (hkl)2 calculation.

With a pair of [uvw] indices a new orthogonal unit cell of c-axis // to [uvw]1 is created (Fig. 4) and with a pair of (hkl) indices the SAED pattern containing these 2 reflections is displayed (Fig. 5). Note that the new orthogonal unit cell can be very large and that in some cases not all atoms of the unit cell are provided.

Both figures can be modified with their attached popup menu (Figures 6a and 6b). This feature is available for all jems drawings, tables, panes and most sliders.
