Jiangyin Xiangjiang Photoelectric Instrument Co., Ltd. is a high-tech enterprise in Jiangsu Province.

Since its establishment 27 years ago, the company has been engaged in the research and development of precision optical products and the production of geodetic mapping instruments with precision machinery, optoelectronics and mechatronics. Among them, the production of high-precision pyramidal reflector prisms has an annual output of about 800,000 pieces, which can range from 5 to 100n/n with a comprehensive angle difference of 180 degrees of 1 to 2 "and is currently one of the few manufacturers that can achieve such high-precision at home and abroad.

The company's innovative development over the past decades has formed advanced technology, technical personnel, equipment and instruments capable of mass production of the highest precision optical cold processing.The company has internationally recognized imported Zhai Klimeda laser interferometer from the United States and 0.5 "infrared total station produced by Leica Company in Switzerland. It can track and test the accuracy of a single pyramid reflector throughout the whole process from the precision of the finished product to ensure that the accuracy of each product in the factory reaches the international level of similar products.

The company has obtained 18 national patents and 8 provincial high-tech products, and many products have been successfully adopted by major national scientific research projects and national defense advanced military products. In 2016, our company shouldered the responsibility of providing high-precision corner prism for the national major scientific and technological project "500-meter spherical radio telescope" astronomical eye project.

The company has been constantly climbing to high, new, excellent, fine and special products, to international brands, with high-quality products, excellent service, won the trust and support of domestic and foreign businessmen and users.
