The PolLux beamline has a toroidal Pt coated first mirror amd a monochromator with a choice of 300 l/mm Ni grating and a 600 l/mm Au grating. A higher order suppression mirror system has also been added between the grating chamber and the exit slits.
The PolLux beamline and its component optics are well described in the following publications:
