Abstract:
1. Process for coating substrates in a continuous flow vacuum coating system with at least two evaporation devices, each device having a respective evaporator tube, comprising: in a first evaporation device, heating and evaporating a first material, in a second evaporation device, heating and evaporating a second material, introducing evaporated material from each evaporation device into the vacuum coating system via the respective evaporator tube in a vapor entry direction, and producing a mixed single layer of evaporated material from the at least two evaporation devices on a substrate, and independently adjusting angle of the vapor entry direction of at least one evaporated tube to the substrate, and setting spacing from the substrate of at least one evaporator tube to produce a desired gradient of the evaporated material in the mixed single layer.
