POLARIMETER

Polarimetry

The POLARIMETER is a versatile UHV-polarimeter for the EUV XUV spectral range which incorporates two optical elements: a phase retarder and a reflection analyzer. Both optics are azimuthally rotatable around the incident synchrotron radiation beam and the incidence angle is freely selectable. This allows for a variety of reflectometry, polarimetry and ellipsometry applications on magnetic or non-magnetic samples and multilayer optical elements.

Selected Applications:
  • Development of ML-optics for Polarisation Steering and Control
  • Full control of Stokes vector (S1, S2, S3) in XUV-range (<1000 eV)
  • Complete at-wavelength characterisation of multilayer optics
  • Measurement of complex reflection or transmission coefficients (Amplitudes and Phases)
  • Polarisation Spectroscopy - Magneto-optics - XMCD, XMLD, T,L-MOKE, Faraday-, Kerr-effect
