ABSTRACT:
Infrared transmitting windows having a diamond support are formed by first depositing diamond (14) on a mold (10) comprising a material which can withstand the optimum diamond growth temperatures. A germanium carbide adhesive layer (18) is deposited on the diamond layer Next, ZnSe, ZnS, or other index-matching material (16) is deposited on top of the diamond coating. Finally, the mold is removed. The end product is a diamond/ZnS(e) IR window requiring little or no polishing of diamond surfaces.
