for ultra-fast crystal orientation and rocking curve measurements
The Omega/Theta X-ray diffractometer is a fully automated vertical three axes diffractometer for orientation determination for various crystals using Omega-Scan and Theta-Scan methods and rocking curve measurements. The large and spacious design can accomodate samples and sample holders up to 450 mm in length and up to 30 kg weight.
All measurements are automated and can be accessed from the user-friendly software interface. Using the Omega Scan, the complete lattice orientation can be determined in on crystal rotation (5 seconds). The Theta Scan is more flexible, but results only in one orientation component per scan.
The tilt angle can be determined with very high precision; up to 0.001° using the Theta Scan. For all other crystal directions the precision depends on the angular difference to the surface perpendicular.
The system is modular and has been equipped with many different extensions for special purposes like shape or flat determination, mapping and diverse sample holders. The sample tilt is detected by an optical measurement, and can be used to correct the resulting orientation.

Our diffractometers are designed for large and heavy single crystals. In particular industrial applications are in the focus of our designs.
Processing large single crystals for wafer production is a key to success in the semiconductor industry. During sawing and grinding, the control of the orientation ensures a good product quality.
Requiring a convenient and fast XRD method for crystal orientation measurements, the industry is the primary application field for the Omega Scan.
Components built from NLO materials have to fulfill high quality standards at the crystal surface and within the bulk material. The surface quality measurement can be combined with XRD orientation determination in one machine.
In orientation measurements on large samples, the alingnment of the specimen within the instrument preselects a certain orientation. With respect to the sample main axis, we can define in-plane and out-of-plane components of the crystal orientation. The Omega Scan is capable of determining all...
In most cases the crystal orientation measurement is a precondition for other processing or measurement steps. The details and peciliarities of each method are not of interest for the most users; they want a reliable result to decide how to go on with their work. Thus having a clear interface and...
