The fabrication and performance evaluation of single‐crystal diamond refractive X‐ray lenses of which the surfaces are paraboloids of revolution for focusing X‐rays in two dimensions simultaneously are reported. The lenses were manufactured using a femtosecond laser micromachining process and tested using X‐ray synchrotron radiation. Such lenses were stacked together to form a standard compound refractive lens (CRL). Owing to the superior physical properties of the material, diamond CRLs could become indispensable wavefront‐preserving primary focusing optics for X‐ray free‐electron lasers and the next‐generation synchrotron storage rings. They can be used for highly efficient refocusing of the extremely bright X‐ray sources for secondary optical schemes with limited aperture such as nanofocusing Fresnel zone plates and multilayer Laue lenses.
