Established in 1958, the Chinese Academy of Sciences Nanjing Astronomical Instrument Development Center is a research base in China, which focuses on the development of large and medium-sized astronomical instruments, and takes into account other opto electromechanical and computer technology integration instruments; According to the requirements of the national science and technology system reform, in December 2001, the company was transformed into a science and technology enterprise (limited liability company) directly under the Chinese Academy of Sciences. The employees directly participated in the shares, 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. At present, the company has more than 300 employees, including one academician of the CAS Member, one academician of the CAE Member, 10 researchers, more than 40 deputy senior professional technicians, more than 60 intermediate and junior engineering technicians, and about 140 senior and intermediate technicians. 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; Scientific and technological achievements such as astronomical telescope optics research, solar multi-channel telescope, solar magnetic field telescope, 1.2-meter infrared telescope, and solar fine structure telescope have won 33 national and provincial scientific research achievement awards, including more than 20 first and second prizes. The 2.16-meter astronomical telescope won the first prize of National Science and Technology Progress Award in 1998 and is now the largest astronomical optical telescope in the Far East.
