Beijing Raytest Technology Co., Ltd. (Abbreviated as "Raytest Technology"), originally founded with technology from the Zhang Shuyuan team, specializes in high-precision laser measurement instruments and equipment, providing clients with comprehensive technical solutions.

 Laser Test Technology produces high-precision measurement instruments including double-refraction dual-frequency laser interferometers, non-contact laser feedback interferometers, optical components - measurement instruments for building materials glass internal stress (and phase delay), laser nanometers, and more, meeting the high-precision measurement requirements of industries such as mechanical manufacturing, microelectronics, and optical processing. The company's product quality, delivery, and after-sales service have received widespread praise.

Raytest Technology is a supplier of laser precision measurement systems and solutions, committed to providing precision testing equipment and measurement solutions to enhance manufacturing capabilities and advance cutting-edge scientific research.

    Raytest Technology is one of the rare companies capable of mass-producing dual-frequency lasers, and it is also a manufacturer of dual-frequency lasers with large frequency differences, high power outputs, and direct orthogonal linearly polarized light outputs.

RayTest Technology's dual-frequency laser directly outputs linearly polarized light without the nonlinear error of converting circularly polarized light to linearly polarized light, achieving higher precision. The product won the Second Prize of the National Technology Invention Award in 2007 (Certificate No. 2007-F-219-2-01-R01).

RayTech is a rare high-tech enterprise that integrates laser fundamental research, laser fundamental device development, and laser application system development. After decades of relentless efforts, it has achieved substantial success.

RaTest Technology's developed and produced waveplate phase delay meters traceable to natural benchmarks are calibration and detection equipment for testing institutions and laboratories.
