Diamond as an Optical Materials
Abstract
CVD diamond, which is mainly polycrystalline, exhibits several materials problems that limit its optical transmission, such as scattering due to large surface roughness and absorption due to defects, nondiamond carbon phases, and impurities. Optical spectroscopy. Raman spectroscopy, cathodoluminescence imaging and spectroscopy, and high resolution electron microscopy are used to examine the defects in the material; however, a relationship between observed defects and optical absorption is not always evident. New polishing methods are promising an ability to produce smooth surfaces in reasonable polishing times.
