The ID21 Scanning X-ray Microscope has been designed to be operated with Fresnel zone plates as focusing optics. For information about the optical principle of the Fresnel zone plates, please have a look at the Zone plates in general section. The following link allows the Calculation of diffraction efficiencies.

 

The zone plates presently in use at ID21 come from:
