Date:2018/10/12 10:14:57

On July 23, 2018, Nuohai Semiconductor, the exclusive distributor of Freiberg Omega/Theta single crystal X-ray diffractometer GMBH, visited Dong Fang Turbine co., Ltd. Chairman Ming Yin, engineers Cheng Haili and Xia Rui from Nuohai held a technical conference at the company. Xia gave a detailed explanation of the principle, accessories, functions, software operation and front-end application of Omega/Theta single crystal X-ray diffractometer. He also introduced the unique Omega scanning rapid measurement of Omega/Theta single crystal X-ray diffractometer, and discussed the unique technology that the equipment can make the orientation map of the whole turbine blade. This meeting lays a good foundation for future cooperation.


About Omega/Theta XRD from Freiberg Instrument GMBH


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. 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.
