Abstract

This paper describes the super smooth surface optical processing methods for optical glass and sapphire components. The super smooth surfaces of optical glass through BFP (Bowl-Feed Polishing) method and sapphire through CMP (Chemo-Mechanical Polishing) method are produced respectively. Microstructures of each processing steps are measured through non-contact method with Zygo NV5022s. Finally, the experimental results are given: the roughness of both optical glass and sapphire component is around 0.5nm (rms or Ra).
