摘要A key technology for fabricating and testing three mirror astigmatism (TMA) was proposed based on a common reference, to overcome the difficulty of manufacturing and aligning large off-axis aspheric systems. The analysis and research of the basic principles involved were presented. When the Root Mean Square (RMS) of the surface error of the primary mirror and tertiary mirrors was better than /10 (for wavelength at 632.8 nm), the primary and tertiary mirrors were measured and aligned with the common reference and the same supporting back plate, with the two mirrors were then being polished by Ion Beam Figuring (IBF). A large TMA system with primary and tertiary mirror apertures of 724 mm247 mm and 632 mm205 mm, respectively was fabricated and tested based on the proposed method. The integrated mirrors were polished by IBF, and the RMSs of the surface error of the primary and tertiary mirrors are 0.019 and 0.017, respectively. 2018, Science Press. All right reserved.
