Results are presented from a program of tests carried out on bulk type IIa (natural) diamond. The objectives were to assess diamond as a material for optical windows exposed to severe environmental conditions, and to determine benchmarks for the performance of synthetic, film-grown diamond. Measurements have been carried out of transmittance and reflectance from the UV to the far-IR, IR transmittance up to 700 degree(s)C, and absorptance at specific CO2 laser wavelengths (determined by laser calorimetry). Water jet impact and simulated sand erosion resistance have been evaluated. The laser-induced damage threshold at 10.6 micrometers has been measured.
