The growth surfaces of CVD diamond films are usually rough with polycrystalline crystallographic habits which presents a severe problem if CVD diamond films are to be used in infrared optics. Several methods are described in this paper in an effort to solve this problem. A polishing process was used to reduce the surface roughness by polishing the rough growth surface with a heated cast iron scaife. For polished films, near 70% transmittance was obtained over the whole range of 600-4000 cm-1, while the transmittance for non-polished films were much lower and varied strongly with the wavenumber. Absorptions believed due to carbon-hydrogen stretching bands and a silicon carbide phase were observed in the transmission spectra of polished diamond films.
