Ultima IV X-ray Diffractometer
Sep 2007
Rigaku Americas Corp.Request Info
THE WOODLANDS, Texas, Sept. 4, 2007 -- The Ultima IV x-ray diffractometer is an advanced general purpose x-ray diffraction (XRD) instrument for materials science, semiconductor, and nanotechnology research and development, as well as for manufacturing quality assurance applications, according to its maker, Rigaku Americas Corp.

The design features a new high-speed detector for 100 times faster measurements, application flexibility provided by patented Cross Beam Optics (CBO), and a 50 percent smaller size than a conventional XRD system, the company said.

A modular "build-up" platform allows users to add additional capabilities as new application requirements arise, including support for high-resolution diffraction, thin-film measurement, microdiffraction and handling very small samples.

Ultima IV is equipped with a unique CBO mechanism that allows user-selectable switching between either a focusing or parallel incident x-ray beam without resetting or realigning the optical system. Both system geometries are permanently mounted and permanently aligned to allow easy changeover for different applications. All other competitive x-ray diffraction systems require system reconfiguration when switching operation of the system between focusing and parallel beam geometries. In addition, new optics for microdiffraction provides data quality close to that provided by a dedicated microdiffraction system.

The Ultima IV, which measures 1100-mm wide, 810-mm deep and 1630-mm high, is also more efficient that a conventional XRD instrument, occupying 50 percent less space and having 20 percent less mass. A reduce footprint means lower facilities overhead for a reduced cost-of-ownership. In addition, the sample stage height is 300 mm lower than a conventional XRD system for ease-of-use, Rigaku said.
