The X-ray crystal orienter​ operates based on the principle of X-ray diffraction. The high voltage generated by the high-voltage transformer acts on the X-ray tube, producing X-rays. When the X-ray is irradiated onto the sample, diffraction occurs when the Bragg diffraction condition (n λ=2dsin θ) is satisfied. Among them, λ is the wavelength of X-rays, d is the spacing between atomic planes inside the crystal, and θ is the angle between the incident X-rays and the crystal plane. The diffraction line is received by the counting tube and displayed on the microampere meter of the amplifier. When using a monochromator, the diffraction line is monochromatized and then received by the counter and displayed on the microampere meter of the amplifier, thereby improving measurement accuracy. The X-ray crystal orienter can accurately and quickly determine the cutting angle of natural and artificial single crystals (piezoelectric crystals, optical crystals, laser crystals, semiconductor crystals), and is equipped with a cutting machine for directional cutting of the above-mentioned crystals. X-ray crystal orienter is an indispensable instrument for precision machining and manufacturing of crystal devices. The X-ray crystal orienter is widely used in the research, processing, and manufacturing industries of crystal materials. The X-ray crystal orienter is easy to operate, does not require professional knowledge or skilled techniques, displays the angle digitally, is easy to observe, and reduces reading errors. The display of the X-ray crystal orientation instrument can be zeroed at any position, making it easy to display the deviation value of the chip angle. The dual angle measuring instrument can work simultaneously, improving efficiency. The X-ray crystal orienter has a special integrator with peak amplification, which improves the detection accuracy. The integration of X-ray tube and high-voltage cable increases high-voltage reliability. The detector high-voltage adopts DC high-voltage module and vacuum suction sample board, which improves the angle measurement accuracy and speed. Overall, the X-ray crystal orienter is a precision instrument based on the principle of X-ray diffraction, which provides important technical support for crystal material research and related applications by accurately measuring the cutting angle of crystals.
