title: Direct polishing of aluminum mirrors with higher quality and accuracy.
abstract: Diamond-turned aluminum mirrors have been widely used in modern optical systems. However, the machined surfaces have characteristic periodic tool marks, which contribute to reduced optical performance by creating effects such as scattering and distortion. This paper develops a new polishing technology to polish aluminum mirrors directly to remove tool marks and improve surface quality and surface accuracy. A Taguchi experiment was used to obtain optimal polishing conditions for reducing surface roughness, and computer-controlled optical surfacing technology was employed for form correction of aluminum mirrors.
