Abstract

Single-point diamond machining is a versatile technique for producing metal optics in conventional as well as unusual shapes. The diamond-turning process is now well enough controlled that high quality, low scatter surfaces can be produced. However, the grooved nature of the surfaces makes it difficult to specify the surface finish and to relate measured roughness values to the performance of a diamond-turned component in an optical system. Specifically, the distribution of the angular scattering from a diamond-turned surface is drastically different from that of a normal polished surface, and the angular scattering can vary greatly from sample to sample.
