test setup for Soleil-Babinet compensator

Abe, Katsuki, Marc

We purchased a Soleil-babinet compensator that will be installed in PCI for future birefringence measurements.

We prepared a test setup on the optical table just in front of PCI clean room (the one where there is the reflectance measurement setup).

We will use the FC spare laser.

We installed 2 OD to have ~ 40 mW of power then 2 steering mirrors(Newport 5204)  to have proper alignment above a lign of holes.

We also brought the required componenents (1 PBS, 1 QWP and 4 HWPs).
