Specialized EUV Optics

Overview


In 2008, Rigaku Innovative Technologies Europe s.r.o. (RITE) became part of the Rigaku Corporation. Originally a research & development facility, RITE now implements cutting edge technologies in the ray tracing, design, manufacturing and testing of “super smooth“ X-ray optics for EUV, XUV and X-ray radiation. The technological combination of extremely smooth optical surfaces and system building techniques allows for metal replication technologies such as Au, Ni, Rh and many more.

RITE also manufactures rotationally symmetric, aspheric X-ray optics for standard and custom designs which can be rapidly developed and manufactured in any quality, for virtually any application, in EUV, XUV and X-ray radiation.

Total Reflection Optics


RITE manufactures and sells Total Reflection X-ray optics. Total Reflection X-ray Optics are specially designed to satisfy both the evolving EUV/XUV industry and the more established Hard and Soft X-ray applications.

RITE has mastered a unique manufacturing technology called replication. This manufacturing technique enables the production of X-ray optics with unique optical features such as low weight, high surface precision (low slope error) and extremely low micro-roughness. Another interesting attribute of Total Reflection Optics is the use of various metallic layers as coatings. The most commonly used materials are Ni, Au, Mo and Ru.
