Diamond X-ray Refractive Lenses with High Acceptance

During the last years X-ray refractive lenses with various design have been manufactured from mono-crystalline diamond by laser ablation with ultra-short laser pulses. The present paper shortly reviews diamond lenses with high acceptance which are intended for transportation of radiation at high-power X-ray accelerator sources. Planar, linear and two-dimensional lenses with parabolic or spherical shape were manufactured and tested at laboratory and synchrotron X-ray sources in focusing and imaging modes. Surface morphology and material quality were also analyzed both with X-ray and conventional methods. Considerations on ways to improve the quality of surface and shape are presented.
