Double Focusing Device for HOPG, Cu or Ge Crystals

Double Focusing Device for HOPG, Cu or Ge Crystals
If ‘a’ is the distance from a radiation source to the monochromator and ‘b’ the distance from the monochromator to the image of the source, then :
The equations show that different vertical and horizontal radius are needed to fulfil to focusing conditions in the two directions.
