laser diode 1A : 1.6mW

z = 20 mm gives distance between blades and last mirror on injection = 171mm

 horizontal cut

Y: 103 mm cut (power halved) (power on dc 1.1) after hav power on dc was 0.55

X:374mm

In the end we recovered normal incidence in both vertical and horizontal directions (within 0.026deg).

We wanted to prepare for linear polariscope measurement but the lockin amplifier showed strange error (undr) related to the chopper signal...

We'll start with polarization camera measurements in the coming days
