2D X-ray metal optics

A parabolic lens geometry of the refracting surfaces is best suited to focus hard X-rays. 2D metal X-ray optics are fabricated using a pressing technique for metals such as Be, Al, and Ni. We produce lenses with a relatively large aperture with radii greater than 50 μm that are capable of focusing a beam along with both transverse directions. Our metal refractive lenses have compact circular frames with a 1 mm thickness and diameter of 12 mm. All refractive lenses are UHV compatible. Please contact us for more detailed information on geometric lens parameters (aperture, web thickness) and on available and possible materials and grades.

A compound refractive lens (CRL) is a set of single X-ray refractive lenses arranged in a linear array to achieve focusing of X-rays in the 2-100 keV energy range at modern synchrotron radiation sources and at free-electron lasers. The main applications of CRL at Megascience facilities are focusing, collimation, monochromatization, suppression of high harmonics, and transport of X-rays. Refractive lens sets are widely used for high-resolution coherent full-field, scanning and diffraction microscopy, darkfield microscopy, interferometry, Fourier analysis, source diagnosis, and micro- and nano-beam generation for HR diffractometry, scattering, and spectroscopy applications. Refractive lenses can be used for efficient beam control on laboratory X-ray sources.
