Fresnel Zone Plates
Offering a wide selection of high aspect-ratio, high-resolution and high-focusing efficiency zone plates from an ample choice of materials, manufactured with electron beam lithography.
- High aspect-ratio Fresnel zone plates
- Best achievable resolution
- Great efficiency across 50 eV – 20 keV
- Outstanding material choices (Au, Ni, Si, SiO2, Ir, Ru, Cr, Diamond)
- Blazed or multi-step designs for optimal focusing efficiency
- World-record achievable resolution based on the Ir-line-doubling technique

Blazed, multi-step and binary written with electron beam lithography electroplated, etched, and coated for multi-keV X-rays with and a wide range of nanostructured sizes down to 7 nm and or a wide as desired.
