An article published by Advanced Materials Technologies investigates making the focusing of x-rays more efficient using kinoforms, which are diffractive x-ray optics. The investigations used a custom-built 3D laser lithography setup and a “40% improvement in scanning transmission X-ray microscopy image resolution” was achieved.
Silson’s silicon nitride membranes (500 𝜇m × 500 𝜇m × 100 nm) in silicon frames (5 mm × 5 mm × 100 𝜇m) were used as substrates, enabling the characterization of the kinoforms in x-ray microscopy experiments
