ASTIX-f: 2-dimensional Focusing X-ray Optics


ASTIX-f: focusing geometry


High Flux Optics

  • high flux (HF) at sample position

  • high integrated pixel intensity


High Resolution Optics

  • small spot size at sample position

  • high resolution (HR) in the detector plane

Focusing 2-dim. X-ray optics in a modified Montel geometry (1) for the generation of 2-dimensional high intensity focused X-ray beams


  • Typical length 60 mm - 150 mm

  • Application with all typical types of X-ray
    sources (rotating and fixed anodes, liquid
    metal jet and micro focus X-ray tubes)

  • Typical spot diameter:
    <30 µm ... 500 µm

  • Convergence: customized

  • Wavelengths: Cr, Co, Cu, Ga, Mo, Ag...

  • High precision vacuum mirror housing
