Abstract
Using a parallel plate reactor we optimized a PECVD process and coated Si02-films on CR 39 lenses with layer-thicknesses of 2,5 trn to 5 I_tIn. Besides high transmittance in the VIS-range we obtained refractive indices between n=1.46 and n=1.49 depending on the process parameters. We achieved deposition rates up to 30 A/s and thickness uniformities of 10 %. The abrasion resistance of these layers were tested with different inethodes and gave better results compared with techniques like lAD or lacquering.
