1) Mosaic spread is the half maximum height peak width of the Cu-Ka
HOPG plates are produced as flat, singly-bent and double-bent shapes. The
monochromators are classified according to mosaic spread.
Grade | Mosaic Spread | Nominal thickness [mm]** | Minimum* size [mm] | Maximum* size [mm] |
---|---|---|---|---|
ZYA | 0.4° ± 0.1° | 2 | 12 x 12 | 50 x 50 |
ZYB | 0.8° ± 0.2° | 2 | 12 x 12 | 50 x 75 |
ZYD | 1.2° ± 0.2° | 2, 4 | 12 x 12 | 50 x 75 |
ZYH | 3.5° ± 1.5° | 2, 4, 6, 8 | 12 x 12 | 75 x 75 |
