Zone plate efficiency for binary zone plates requires high aspect ratio structures which can survive high flux imaging systems. The “Oxide Interlock” option creates small interconnecting channels between metal zone of silicon dioxide which is transparent to hard X-rays and does not swell or distort, even when not under vacuum. These have been shown to significantly increase the zone plate efficiency and lifetime.

Custom designs and frame sizes can be developed for specific applications. We are able to fabricate devices down to 0.1 mm and below. Our standard frame sizes are 5 mm x 5 mm and membrane thickness can be down to 50 nm while the 100 nm thickness is ideal for energies above 5 keV. We also offer silicon carbide membranes for those requiring long-lifetime membranes.
