Model DX-4A
Function: it is an orientation unit of double-crystal diffraction in high precision of higher intensity, mainly used to measure high-precision crystal wafer or other mono-crystal materials.
Characteristics: in high precision only measure small-size ingots or wafers of weak diffraction capacity.
