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.
