The TDF series X-ray crystal analyzer is a large-scale analytical instrument used to study the internal microstructure of substances. It is mainly used for single crystal orientation, defect inspection, determination of lattice parameters, determination of residual stresses, study of the structure of plates and rods, study of the structure of unknown substances, and single crystal dislocations. A X-ray crystal analyzer is a precision instrument that uses the principle of X-ray diffraction to analyze and determine the internal structure and composition of substances.

1. The working principle of X-ray crystal analyzer:

The X-ray crystal analyzer is based on Bragg's law, which states that when X-rays are irradiated onto a crystal, diffraction occurs at a specific angle, forming diffraction spots or peaks. By measuring the angles and intensities of these diffractions, the internal structure and composition of the crystal can be inferred.
