In the field of modern technology, many high-tech products—from smartphone screen substrates to core components of laser generators—rely on a fundamental material: synthetic single crystals. The precision of the cutting angle of these crystals directly determines the performance and yield of the final products.

The X-Ray Orientation Analyzer is an indispensable instrument in the precision manufacturing of crystal devices. Utilizing the principle of X-ray diffraction, it accurately and rapidly measures the cutting angles of both natural and synthetic single crystals, including piezoelectric crystals, optical crystals, laser crystals, and semiconductor crystals.

Dandong Tongda Science and Technology Co., Ltd. offers a range of reliable X-Ray Orientation Analyzers tailored to the research, processing, and manufacturing needs of the crystal materials industry.

01 Versatile Machine for Diverse Crystal Orientation Needs

Dandong Tongda's X-Ray Orientation Analyzers primarily include models such as the TYX-200 and TYX-2H8.

The TYX-200 model boasts a measurement accuracy of ±30″, with a digital display and a minimum reading of 10″. The TYX-2H8 model is an improved version of the TYX-200, featuring enhancements in the goniometer structure, load-bearing track, X-ray tube sleeve, support body, and an elevated sample stage. These improvements enable the TYX-2H8 to handle samples weighing 1–30 kg with diameters of 2–8 inches. It retains a digital angle display and a measurement accuracy of ±30″.

02 Advanced Technical Features for User-Friendly Operation

Dandong Tongda's X-Ray Orientation Analyzers are designed with practicality and reliability in mind. Their user-friendly operation requires no specialized knowledge or advanced skills from the operator.

The instrument features a digital angle display, ensuring intuitive and easy-to-read measurements while minimizing the risk of misreading. The display can be zeroed at any position, allowing direct reading of the wafer angle deviation.

Some models are equipped with dual goniometers for simultaneous operation, significantly improving detection efficiency. A special integrator with peak amplification enhances measurement accuracy.

The X-ray tube and high-voltage cable adopt an integrated design, improving high-voltage reliability. The detector high-voltage system uses a DC high-voltage module, and the vacuum suction sample stage further enhances measurement accuracy and speed.

03 Dedicated Sample Stage Designs for Various Testing Needs

To meet the measurement requirements of samples with different shapes and sizes, Dandong Tongda offers a variety of specialized sample stages:

• TA Sample Stage: Designed for rod-shaped crystals, it features a load-bearing track and can test crystal rods weighing 1–30 kg with diameters of 2–6 inches (expandable to 8 inches). This stage can measure reference surfaces of rod-shaped crystals as well as surfaces of wafer-shaped crystals.

• 
  

• TB Sample Stage: Also designed for rod-shaped crystals, it includes a load-bearing track and V-shaped support rails. It can test crystal rods weighing 1–30 kg, with diameters of 2–6 inches (expandable to 8 inches) and lengths of up to 500 mm. It measures end faces of rod-shaped crystals and surfaces of wafer-shaped crystals.

• 
  

• TC Sample Stage: Primarily used for detecting the outer reference surfaces of single-crystal wafers such as silicon and sapphire. Its open-design suction plate avoids X-ray obstruction and positioning inaccuracies. The stage's suction pump securely holds wafers sized 2–8 inches, ensuring precise detection.

• 
  

• TD Sample Stage: Designed for multi-point measurements of wafers such as silicon and sapphire. Wafers can be manually rotated on the stage (e.g., 0°, 90°, 180°, 270°) to meet specific customer measurement needs.

04 High-Performance Model for Large Sample Challenges

For large and challenging sample detection, Dandong Tongda's X-Ray Orientation Analyzers demonstrate exceptional performance. The TYX-2H8 model, for example, is particularly suitable for orienting sapphire crystal ingots and rods.

This instrument supports measurements of sapphire A, C, M, and R crystal orientations, with an adjustable measurement range of 0–45° via electric automation. Its technical specifications are impressive:

• Copper-target X-ray tube with grounded anode and forced air cooling.

• Adjustable tube current: 0–4 mA; tube voltage: 30 kV.

• Operation via computer or touchscreen control.

• Synchronized movement of the X-ray tube and detector; electric-driven rotary table.

• Total power consumption: ≤2 kW.

Most notably, its sample handling capacity includes crystal ingots weighing up to 30–180 kg, with maximum dimensions of 350 mm in diameter and 480 mm in length. These capabilities make it suitable for large sample detection in most industrial scenarios.
