Realignement of the beam after some issue with the polarizer alignement :

start : x=323.565  ; y= 64.3750; z=60

distance between blade and last mirror = 146mm

vertical cut of the beam ; x=314  ; y= 100; z=20

horizontal cut of the beam ; x=360  ; y= 180; z=20

max DC = 0.234V

y(166.500)=  9.14e-5  = y(146.943)

x(313.700)  = 7.14e-5 = x(333.480)

--> CENTER : x=323.59 ; y =156.721
