Today I moved the clean booth that was in the storage room on the test setup for the Soleil-Babinet.

Indeed we want to install it later on the PCI setup and want to limit possible dust contamination.

All the optics that were below (seems to be TAMA mirrors) and screws, magnets, etc... are now inside the clean booth of the microscope.

The setup is now ready for calibration of the Soleil-Babinet and we plan to use pure s-polarization for this.
