Changchun Institute of Optics, Fine Mechanics and Physics

It was founded in 1952 as the Institute of Instrumentation of the CAS, by a group of scientists led by Wang Daheng. It was later renamed as the Changchun Institute of Optics and Fine Mechanics. The current name was adopted in 1999 when the institute was merged with the Changchun Institute of Physics, headed by Xu Xurong. In December 2025, Reuters reported that the institute had achieved a breakthrough in integrating extreme ultraviolet light into a prototype extreme ultraviolet lithography machine's optical system in early 2025, allowing it to become functional. == Functions ==

The institute focuses on luminescence, applied optics, optical engineering, and precision mechanics and instruments. It is involved in a number of technology ventures based out of the nearby CAS Changchun Optoelectronics Industrial Park with total assets worth US$403 million. The institute offers undergraduate, master's and doctoral education programs. == CGSTL ==

The institute includes the Chang Guang Satellite Technology Corporation (Charming Globe or CGSTL), a commercial offshoot of the institute which manufactures remote sensing satellite buses and unmanned aerial vehicles (drones). Chang Guang Satellite Technology owns Jilin-1 satellite constellation. In September 2024, it launched six Jilin Kuanfu satellites. According to the Norwegian Communications Authority, CGSTL is serviced by Kongsberg Satellite Services. In 2023, the United States imposed sanctions on Chang Guang Satellite Technology for providing geospatial intelligence to Wagner Group during the Russian invasion of Ukraine. According to the United States Department of State, Chang Guang Satellite Technology Corporation provides geospatial intelligence to the Houthis to target U.S. warships in the Red Sea crisis. == See also ==
