Not Available Aluminum nitride (AlN) has the potential to meet the requirements of mid-wave infrared seeker windows on high-speed missiles. However, ALN has not been produced with the required optical properties of less than 2% scatter at a wavelength of 4 microns, an absorption coefficiency less than 0.1/cm at a wavelength of 4 microns and a transmittance of 74% at 4 microns. Transparent AlN has been produced in very thin films but not in required thickness of 2mm or greater required for seeker windows. In cursory experiments, MER has demonstrated a deposition process for producing transparent AlN and this deposition process has produced other materials in thicknesses up to 12mm thick. This economical rapid deposition process will be optimized to produce AlN with 2 mm or greater thicknesses with the desired optical properties.
