Table 1. Details of the optical elements of B07 branch C.
All mirrors and gratings are based on Si single-crystal substrates. M1c has a 5–10 nm Cr binding layer between substrate and coating; the other optical elements have no binding layers.

| Channel-cut crystal monochromator | None (Si) | 20.133 m |
| cPGM mirror M2c (plane) | Pt/Rh (40 nm) | 21.334–21.784 m |
| cPGM grating 400 lines mm−1 | Au (40 nm) | 21.824 m |
| cPGM grating 600 lines mm−1 (blazed) | Pt/Au (20/30 nm) | 21.824 m |
| cPGM grating 1200 lines mm−1 | Au (40 nm) | 21.824 m |
| Mirror M3c (cylinder) | Rh (50 nm) | 23.324 m |
| Mirror M4c (cylinder) | Rh (50 nm) | 33.324 m |
