Optical Payload Manufacturing & AIT Center (Changchun)

The Changchun optical payload manufacturing AIT (assembly, integration and test) center focuses on the design, development, testing, and validation of large-aperture optical remote sensing satellite payloads, with a strong technical foundation in space remote sensing equipment, optoelectronic detection devices, and optoelectronic instruments. The facility independently develops complete optical remote sensing payloads and their core components, with capabilities in payload design, assembly, integration, and testing, including wavefront and imaging-quality evaluation using Rayleigh criterion, wavefront maps, spot diagrams, and MTF (modulation transfer function) analysis. It provides comprehensive optoelectronic systems, instruments, and products for defense, industrial, and regional users.
