“…Another popular material for compound refractive lenses are polymer materials, such as polymethyl methacrylate (PMMA). Lenses are often prepared in combination with 3D printing technology [17]. A resolution of around 100 nm can be obtained [18].…”

The compound refractive lens (CRL) is a commonly used X-ray optical component for photon beam conditioning and focusing on the beamlines of the X-ray facilities. The normal preparation materials are beryllium, aluminum, silicon of current lenses, and they all suffered from high heat load fatigue and short pulse damage risks. Hard materials based CRL is engaged attention for the advanced X-ray application. Sapphire crystal has the advantages of high density, high melting point, low thermal expansion coefficient. In this paper, properties of the refraction and absorption ratio of Sapphire and parameters of Sapphire lenses of effective aperture, transmittance, resolution, number of lenses needed for a certain focus, are taken into account for the CRL design, comparing with those of several common materials as well. The calculation results show that the performance of the sapphire lens is better than that of the aluminum lens and silicon lens, and inferior to that of the beryllium lens and diamond lens, but the number of lenses used is less. In the meantime, performances of sapphire lenses focusing are simulated and thermal effects on lenses are analyzed. Analysis and discussion are carried out under the same conditions as the metal Aluminum ones. The focusing simulation shows that the sapphire lenses can obtain a smaller spot with more intensity. The thermal analysis indicates that the temperature during use of the sapphire lens is much lower than the melting point of sapphire, and the thermal deformation is negligible.

“…Recently, the use of 2D refractive lens arrays, fabricated either by additive manufacturing of a polymer with low radiation stability or by an embossing process of polyimide foils using a needle with paraboloid tip, were demonstrated for energies below 15 keV and for a field of view (FoV) of 1 mm 2 and 6.5 × 6.5 mm 2 , which limits the scope of the samples studied [10,11]. Fabrication of 2D CRLs for higher energies by these techniques is a challenging task at the moment.…”

Development of an Array of Compound Refractive Lenses for Sub-Pixel Resolution, Large Field of View, and Time-Saving in Scanning Hard X-ray Microscopy

A two-dimensional array of compound refractive lenses (2D array of CRLs) designed for hard X-ray imaging with a 3.5 mm2 large field of view is presented. The array of CRLs consists of 2D polymer biconcave parabolic 34 × 34 multi-lenses fabricated via deep X-ray lithography. The developed refractive multi-lens array was applied for sub-pixel resolution scanning transmission X–ray microscopy; a raster scan with only 55 × 55 steps provides a 3.5 megapixel image. The optical element was experimentally characterized at the Diamond Light Source at 34 keV. An array of point foci with a 55 µm period and an average size of ca. 2.1 µm × 3.6 µm was achieved. In comparison with the conventional scanning transmission microscopy using one CRL, sub-pixel resolution scanning transmission hard X-ray microscopy enables a large field of view and short scanning time while keeping the high spatial resolution.

The quasi-optical transmission line with optical contrast close to 1 is considered. Such devices can be used to study the effect of laser radiation on biological media, in microwave, terahertz, optical and X-ray wavelength ranges, as well as in acoustics. The use of composite refractive lenses, which are a set of identical spherical lenses arranged one after another on the same optical axis and with a refractive index close to one, reduces the loss of reflection in such a lens. Reducing the focal length in such refractive lenses is possible by increasing the number of refractive surfaces.
