We use different substrates for different purposes. For example, polyimide for low-energy applications, silicon for phase gratings, and graphite for absorption gratings.

Our standard set of gratings features 6 µm period parallel lines and is designed for use at 40 keV.

Other Symmetric Grating Sets:

• 8 keV, 2.4 µm period, 50 mm x 50 mm
• 20 keV, 4.8 µm period, diameter: 70 mm
• 55 keV, 8.0 µm period, diameter: 100 mm

Custom Grating Kits:

We offer custom production of grating kits to your specifications.
Options include adaptation to other energies, layout area, 2D gratings (hole arrays for Hartmann sensors), different periods.
