Specialized EUV Optics


Rigaku Innovative Technologies Europe s.r.o. (RITE) implements cutting edge technologies in the ray tracing, design, manufacturing and testing X-ray optics for EUV, XUV and X-ray radiation. RITE’s primary focus has been research & development projects which have resulted in an extension of Rigaku’s X-ray optics and detectors for EUV/XUV, Hard and Soft X-rays.

To achieve larger and bigger optics, RITE is using manufacturing techniques other than replication. Proprietary techniques and processes enable RITE to commercially produce optics with a diameter of up to 300 mm and segment lengths of up to 250 mm. When several segments are combined, optics lengths of up to 1000 mm are easily produced.
