Abstract
In this study, magic and deformable mirrors were fabricated using an additive manufacturing (AM) process. This was to confirm the magic mirror effect caused by the grinding pressure of the mirrors produced by the AM-based manufacturing process. For verification, eight magic mirrors were fabricated under different conditions. The results showed that the magic mirror effect occurred on two mirrors with a diameter of 10 mm and wall thicknesses of 0.1 and 0.2 mm. AM is easy to machine thin-wall; therefore, a pneumatically deformable mirror was fabricated. The shape-control performance through air pressure fluctuations was confirmed. In this study, magic mirrors and deformable mirrors have been successfully fabricated using additive manufacturing technology. The method proposed in this study enabled the efficient production of lightweight and thin mirrors.
