*The Nanjing Astronomical Instrument Research and Development Center was founded in 1958 and is the largest research and development base in China, mainly focusing on the development of large and medium-sized astronomical instruments, while also taking into account other integrated optical, electromechanical, and computer technology instruments; According to the requirements of the technological system reform, in December 2001, a technology enterprise (limited liability company) directly under the central government was transformed, and employees directly participated in the shareholding, which increased their risk awareness and sense of responsibility. The company obtained the self operated import and export rights in February 2003, becoming the largest production enterprise in the same industry with self operated import and export qualifications. The registered capital of the company is 38.56 million yuan, the legal person's assets are 120 million yuan, and it covers an area of more than 160 acres. The company currently has more than 300 employees, including 1 academician, 1 academician, 10 researchers, over 40 associate senior professional and technical personnel, over 60 intermediate and junior engineering and technical personnel, and about 140 senior and intermediate skilled workers. The company has research and design advantages in comprehensive disciplines such as instrumentation, optics, precision machinery, automatic control, and computer technology; It is the awarding point for doctoral and master's degrees in disciplines such as astrophysics, astronomical technology and methods; There are rare large and medium-sized optical cold processing equipment (optical workshop), precision mechanical processing equipment, and detection devices in China; It holds a domestic position in optical processing techniques such as birefringent crystals, non spherical surfaces, especially off-axis non spherical surfaces, and millimeter wave panel technology for radio telescopes. The company focuses on astronomical technology and methods as its research direction, mainly developing star observation instruments, solar observation instruments, artificial satellite observation instruments (including range instruments), astronomical measurement instruments, radio astronomy instruments, and other integrated optical, electromechanical, and computer instruments; The optical research of astronomical telescopes, multi-channel solar telescopes, solar magnetic field telescopes, 1.2-meter infrared telescopes, and solar fine structure telescopes have achieved 33 scientific and technological achievements, including more than 20 first and second prizes at the provincial level of the Chinese Academy of Sciences. The 2.16-meter astronomical telescope won the first prize for scientific and technological progress in 1998 and is now the largest astronomical optical telescope in the Far East.
