Multi-Foil Optics for EUV and X-ray radiation

Custom designed KB and Lobster eye optics with a wide FOV

Multi-foil optics

Extending the replicated optics technologies, Rigaku Innovative Technologies Europe (RITE) designs and produces Multi Foil Optics (MFO). These specialty optics are perfectly suited for applications where low energies and a very wide field of view is needed.

RITE's products represent the cutting edge in the field of X-ray optics. RITE has outstanding capabilities in ray-tracing, designing, manufacturing and testing of Multi-Foil Optics (MFO). The MFO in general is a soft X-ray and EUV optics which consists of two perpendicular sets of very thin reflecting mirrors, where photons are reflected at grazing angles. MFO is assembled from thin foils (typ. glass, silicon or metal). Various arrangements and geometries are possible (e.g. Lobster Eye, Kirkpatrick-Baez). Rigaku Innovative Technologies Europe manufactures 1D and/or 2D MFO optics. Rigaku offers custom designs which can be rapidly developed and manufactured.
