摘要：
A manufacturing technology of mirrors for free-space optical communication is presented: a thin layer of Nickel is deposited on a master and bonded on a light-weighted structure by adhesive. After separation, the master is ready for another cycle. The process is cost-effective because only the master needs to be of optical quality. The structure is machined by traditional tooling, with figure errors compensated by the adhesive. Its curing time defines the process throughput to one mirror per day per master. Several 200 mm-aperture Ritchey-Chretien telescopes have been manufactured and tested.
