Zone Plates and Custom Options

Fresnel zone plates are diffractive optics used for focusing extreme ultraviolet (EUV) and X-ray radiation. These components are fabricated with outer zone width resolutions as fine as 18 nm for soft X-rays and 30 nm for hard X-rays. They are critical components in synchrotron-based microscopy techniques such as STXM (Scanning Transmission X-ray Microscopy) and TXM (Transmission X-ray Microscopy), as well as in ptychography and phase contrast imaging. Custom options are available, including different materials (Au, Cu, Ni, W, Pt), the addition of central stops to block zero-order diffraction, and custom frame sizes.
