The picture shows the appearance of the stress meter

The equipment is a precision testing equipment integrating precision optics, mechanical engineering, automation control and software programming. Its detection accuracy of stress birefringence is better than 0.1nm/cm, which can realize the scanning test of large quartz glass of 800mm×500mm size. The degree of fineness of the stress distribution is adjustable, and the distribution results are imaged and the report is presented.

The device adopts fast scanning and open structure design, which is easy to operate, short in test cycle, good in test efficiency and repeatability. The test results are in good agreement with foreign imported instruments and achieve good expected results.

In recent years, Shanghai Hengyi Optical Precision Machinery Co., Ltd. has scientifically positioned and laid out the company's development and optical-related precision processing and testing equipment bases from a strategic perspective. In large-caliber interferometers, intelligent ring polishing machines, and opto-mechatronics equipment. In the field of custom-made and other areas, we have been digging deeper and expanding, and we are committed to building a younger technical team and occupying the commanding heights in this field in China.

The “Full-automatic large-size optical glass stress tester” delivered this time marks a big step for the company from the static field of electro-optical integration to the development of dynamic high-precision automatic control machine. The company's R&D team is in opto-mechatronics. Systematic training in automatic control, software and integration has laid a solid foundation for the subsequent strategic layout of the company.
