We start redefining the subapertures: we modify the SX ones (20150330_170400).

11:00: we start to work on the beam shaping procedure
Conversion between LBC steps and LFS steps to keep the same spot dimension:
42 LBC/LFS steps
LBC makes 1000 steps to move the plates between 10 and 50deg incidence angle. LFS makes 250k steps to move the lenses of 25mm.
The longitudinal focus shift introduced by a tilted parallel plate is: Dz= (n-1) l / n, where l is the optical path in the glass: l= t / cos (theta_r), where t is the plate thickness and theta_r is the refracted angle: theta_r= arcsin( sin(theta_i) / n), where theta_i is the incidence angle.
