Jiangyin Xiangjiang Optoelectronic Instrument Co., Ltd. is a High-tech Enterprise in Jiangsu Province. Founded on May 22, 1995, the company has long been engaged in the R&D and production of precision optical products, supporting precision machinery, as well as opto-mechatronic geodetic surveying instruments. Through decades of innovative development, the company has built up mature processes, professional technical personnel and complete equipment for mass production of precision optical cold processing. The enterprise is equipped with a Zygo laser interferometer imported from the United States and a 0.5" infrared total station manufactured by Leica Geosystems, Switzerland. It enables full-process tracking and inspection covering individual corner cube retroreflectors up to finished products, ensuring every delivered product meets specified technical accuracy requirements. The company has obtained a number of national patents. Multiple products have been successfully adopted in key national scientific research projects and supporting national defense research programs. In 2016, the company supplied high-precision corner cube retroreflectors to the Five-hundred-meter Aperture Spherical Telescope (FAST, also known as China Sky Eye), a major national science and technology project. The products passed acceptance by the project owner and were officially put into service. The company continues to focus on the R&D and manufacturing of high-precision, differentiated optical instruments with reference to the technical standards of international equivalent products. Supported by consistent and reliable product quality and comprehensive supporting technical services, it has won long-term recognition and sustained cooperation from customers at home and abroad.
