Abstract
WE PROPOSE TO DEVELOP AN ANTI-REFLECTION (AR) COATING FOR DIAMOND FILMS OPTIMIZED TO ENHANCE THE TRANSMISSION IN THE 8 TO 12 MICRON REGION OF THE SPECTRUM. THE METAL-OXIDE MATERIALS TO BE EVALUATED HAVE GOOD OPTICAL TRANSMISSION IN THIS SPECTRAL REGION AND REFRACTIVE INDICES NEAR THE OPTIMUM VALUE OF 1.55 FOR A DIAMOND AR COATING. SINCE A SECONDARY PURPOSE OF THE COATING IS TO PROTECT THE DIAMOND FROM OXIDATION AT HIGH TEMPERATURES (1000OC), THE METAL-OXIDES ARE CHOSEN WITH HIGH MELTING TEMPERATURES. INITIAL COATINGS WILL BE DEPOSITED USING ION ASSISTED DEPOSITION. THE OPTICAL PROPERTIES OF THE AR COATINGS WILL BE MEASURED AND COMPARED WITH UNCOATED DIAMOND FILMS. NANOCRYSTALLINE DIAMOND MATERIAL WILL BE USED AS WINDOW MATERIAL TO MINIMIZE THESCATTERING LOSSES. ADHESION TO THE DIAMOND SUBSTRATE WILL BE EVALUATED.
