Two X-ray mirrors for ID26 Beamline

Supply of two flat X-ray mirrors for white-beam mirror system for ID26 beamline. The mirror substrates will each provide four distinct optical apertures differing only in their surface coatings. Supply of coated mirror optics only (no optomechanics) Mirror 1: Material Single crystal silicon Overall dimensions (LxWxH) 420x70x80 mm3 3 flat zones 1 sagittal cylinder R=150 mm Meridional Slope error for all zones (rms) <0.2 µrad Surface roughness (rms) <3 Å Coatings Pt, (Si), Pd, Cr Mirror 2: Material Single crystal silicon Overall dimensions (LxWxH) 1070x70x95 mm3 4 flat zones Meridional Slope error for all zones (rms) <0.2 µrad Surface roughness (rms) <3 Å Coatings Pt, (Si), Pd, Cr
