DX-9 Rocking-Curve Orientation Unit
Functions:
It is a semi-automatic one to measure the angle to determine the surface defects of mono-crystal materials. In operation the SCM System collects the real-time data and delivers them to the computer analysis system for data processing to get the peak angle and FWHW values, which determine the crystal-surface growth completeness.
Characteristics: it is nondestructive during the test process. It gets a feature of higher precision and accuracy in testing repeatedly, which makes the test simple, quick and easy in operation.

For a common sample a
test takes 18 s.( scan-angle range ±5ˊ), test can be done for once or many times. With the same
sample, repeated measuring the identical point ≤±1″(measured with
standard quartz polished-piece plane 10ī1 or sapphire substrate polished
piece ).
