@ ~9:00-10:00 LT we swap the LB_DB_AMP_L1 lens from F=0.4m to F=0.5m. we keep the same position for the lens (~ 0.655 m from neoVAN).

the beam waist should be 829 um at 2,1 m from LB_DB_AMP_L1
this means a beam size at DB_AMP_QD_FF = Dvg*(F=0,813 m) = 332 um
this means the same beam size at the DB_AMP_PD_3mm, the PD with monitor the AMPL power (3mm diam)

The beam size at DB_AMP_QD_NF = 1047 um (located 0.465 m from LB_DB_AMP_L1)

We install a UVFS plate with 1 side AR coated after the LB_DB_AMP_L1 to feed a camera and monitor the neoVAN beam profile in the far field
of this lens (F=0.5 m). The AOI is to be confirmed together with the distance to the lens.
The beam is left miscentered on the camera waiting for the configuration of the latter
