Summary
Nanjing Institute of Astronomical Optics & Technology is categorised as a Limited Defence Partner based on the following indicators:
- Defence advisor
- 0 indicators
- Defence award
- 1 indicators
- Defence funding
- 2 indicators
- Defence laboratory
- 2 indicators
- Military-technology patent
- 2 indicators
- Research collaboration with defence entities
- 3 indicators
A limited defence partner contributes to the development of China’s defence capabilities in ways that are limited in time, frequency, scope or scale. Evidence indicates that participation has either ceased or if it persists, it is narrow in scope, not institutionalised and occurs through isolated or infrequent activities led by individual researchers, rather than through sustained programmes or organisational commitments.
Rules-based framework
| Rule | Resulting category |
|---|---|
| Two or more indicators = 4 | Core defence partner |
| One indicator = 4 and two indicators = 3 or Three or more indicators = 3 | Regular defence partner |
| One indicator = 4 and one indicator = 3 and all other indicators = 1 or 2 or Two indicators = 3 and all other indicators = 1 or 2 | Limited defence partner |
| All indicators between 0 and 2 | Civilian institute |
| Three or more indicators = 0 | Insufficient data |
Note: All indicators operate on a 0 to 4 scale. There are a total of six indicators.
For more information on the graded scales see the user guide.
Defence advisory roles
Members of the leadership of the Nanjing Institute of Astronomical Optics & Technology have possibly not served on any defence-related expert committees. However, because the underlying data are outdated and lack sufficient detail, this assessment is made with low confidence, and such service by any member of the leadership cannot be fully ruled out.
Defence awards
Available information indicates that researchers and projects linked to the Nanjing Institute of Astronomical Optics and Technology are unlikely to have received any defence awards. However, because the available information is somewhat outdated, the assessment is made with medium confidence, particularly with respect to any more recent awards.
Defence funding
Between 2021 and 2025, researchers from the Nanjing Institute of Astronomical Optics & Technology authored four publications funded by Chinese defence entities, placing the institute in the 10th percentile among the CAS institutes included in this analysis. Of the 1,192 authors affiliated with the Nanjing Institute of Astronomical Optics & Technology who published during this period, four (<1 per cent) had at least one defence-funded publication. However, it is not possible to attribute specific funding to individual researchers based solely on publication data.
Defence laboratories
No publicly available information suggests that this institute hosts or is affiliated with any known defence laboratories. However, two laboratories, not categorised as defence laboratories, referenced links to defence activities on their Chinese‑language website. General references to promoting national security or defence are common on CAS laboratory websites. These statements often serve as broad affirmations of alignment with national policy objectives – a routine expression of support for government priorities that can be important for maintaining institutional standing, access to funding or official recognition – rather than firm evidence that the laboratory conducts defence-related research.
Astronomical and Space Mirror Technology Research Laboratory
| Name | Astronomical and Space Mirror Technology Research Laboratory [天文与空间镜面技术研究室] |
|---|---|
| Research topics | Mirror development technologies (polishing, coating and inspection) |
| Defence ties | According to its website, this laboratory promotes 'astronomical technology to serve national strategy and national security'.[1] |
Key Laboratory of Astronomical Optics Technology
| Name | Key Laboratory of Astronomical Optics Technology [天文光学技术重点实验室] |
|---|---|
| Research topics | Optical/infrared telescopes, astronomical spectroscopy, solar telescopes |
| Defence ties | According to its website, this laboratory 'leverages its strengths for national security projects'.[2] |
Military-technology patents
Between 2021 and 2025, the Nanjing Institute of Astronomical Optics & Technology was granted three military-technology patents, placing it in the 51st percentile among the CAS institutes included in this analysis. A total of 13 inventors affiliated with the Nanjing Institute of Astronomical Optics & Technology were listed on these patents.
Research collaboration with defence entities
Between 2021 and 2025, researchers from the Nanjing Institute of Astronomical Optics & Technology co-authored 220 publications with at least one Chinese defence entity, placing the institute in the 29th percentile among the CAS institutes included in this analysis.
These collaborations include 4 publications with PLA academic institutions, 162 with defence laboratories, 53 with members of the Seven Sons of National Defence and 21 with members of the Seven Sons of Ordnance Industry.
Of the 1,192 authors affiliated with the Nanjing Institute of Astronomical Optics & Technology who published during this period, 232 (19 per cent) had at least one defence-related collaboration.
