Article Synopsis
- Silicon carbide (SiC) aspheric mirrors are lightweight with high stiffness, essential for space optical systems, but their processing is challenging due to their hardness and complex composition.
- This paper proposes an innovative processing method combining ultra-precision shaping, rapid polishing with fluid, and magnetorheological finishing (MRF) to achieve high precision and low defects in SiC mirror fabrication.
- The process was validated on a 460 mm SiC mirror, dramatically reducing surface errors from 4.15 μm to a root-mean-square (RMS) of 7.42 nm in just 216 hours, indicating potential for mass production.
