Process characteristics

NEW Tinted Gradient AR process: The tinted gradient is applied directly in the AR-process in highest quality (100% stable tinting results) without the need of a separate tinting machine. You can now coat different indices (also high index) as well as freeform lenses in the same batch. Moreover, you have a maximum flexibility in the design of your gradient with regards to color, length, position and intensity. Even customized gradient shapes are possible. Moreover, Tinted Gradient AR can be combined with hydrophobic and AR-coatings in one and the same process as well as high fashion mirror coatings in a separate process.
