The next generation light sources will require x-ray optical components capable of handling large instantaneous and average power densities while tailoring the properties of the x-ray beams for a variety of scientific experiments. Diamond being radiation hard, low Z material with outstanding thermal properties is proposed for front pre-focusing optics applications. Euclid Techlabs had been developing x-ray refractive diamond lens to meet this need. Standard deviation of lens shape error figure gradually was decreased to sub-micron values. Post-ablation polishing procedure yields ~ 10nm surface roughness. In this paper we will report on recent developments towards beamline-ready lens including packaging and compound refractive lens stacking. Diamond lens fabrication is done by femtosecond laser micromachining. We had been using this technology for customization of other beamline components. Several application cases will be highlighted in this presentation: diamond anvils, x-ray flow cells and in-beam mirrors.
