Abstract

This paper will report on the properties and applications of polished polycrystalline diamond optical components produced by Chemical Vapor Deposition and fabricated in sizes and geometries suited to several IR window and some applications. Data will be presented on optical quality CVD diamond materials that has been synthesized in a production plant and then optically finished sufficiently flat and parallel for operation as passive IR imaging windows or exit windows for high power CO_s lasers. The processing tolerances achieved on the windows as well as data on the material's transmission and IR imaging properties will be presented. The current state of the art in the manufacture of CVD diamond optical components will be presented and we report for the first time: (1) precision, planar IR imaging windows up to 120 mm in diameter, (2) 70mm diameter, fully polished hemispherical domes, and (3) shallow diamond lenses suitable for use as laser output-coupling windows. Polished CVD diamond windows and domes are very well suited to exploitation in adverse environments; in particular, for use as protective windows in passive long wave IR imaging applications. It is essential that the precision and finish of the components are suitable for such uses and this paper will describe the characterization of the geometrical tolerances that can currently be achieved with CVD diamond as well as other relevant properties.
