[ATM] Aligning Ronchi screens
The alignment isn't that hard as you will note that the lines will be
sharpest only at one point on the surface and will disappear in the rest of
the surface. When you get the test setup, rotate one grating until the
lines are equally sharp over the whole mirror.
This should work right (my famous last words!).
