Information × Registration Number 0203U006650, 0100U004820 , R & D reports Title The formation of film multilayer structures of diamond-like carbon and compounds of rare-earth metals for optical and protective coatings with improved physico-mechanical properties. popup.stage_title Head Gontar O.G., Registration Date 02-07-2003 Organization V.Bakul Institute for Superhard Materials popup.description2 An experimental technology of the a-c:H film deposition onto optical elements of Si and Ge and onto multilayer antireflection coatings of the IR region has been devised. Experimental samples of optical IR elements with a higher (98%) transmission in the 8-12 mm range and a composite hardness of about 3.2-5.0 GPa have been prepared. The methods for qualitative and quantitative analysis of the elementary composition of multilayer interference coatings have been developed.
