Sample size up to 450 mm Appropriate for production quality control and research User friendly and cost effective Convenient sample handling and easy to operate Advanced, user-friendly software Low energy consumption and operating costs Modular design and flexibility Various upgrade options Customization to the users' requirements Omega-scan diagram (SiC) Turbine blade, map of one orientation component (Si, Ge) wafer, orientation map lattice parameter map Established Omega-scan method 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. Highest precision Measurement speed: < 5 secs/sample Easy integration into process line MES and/or SECS/GEM interfaces Typical standard deviation tilt (example: Si 100): < 0.003 °, minimum < 0.001 ° Applications Crystal Surface Orientation Mapping Even within a single crystal, slight variations in crystal orientation can occur across the surface, often due to internal strains from lattice defects. Similarly, well-grown thin films can… Learn more 3D Mapping of Crystalline Turbine Blades The high-temperature creep resistance of turbine blades made from single-crystal NI-superalloys is influenced by the deviation from the target orientation.
