Abstract:
1. A method for coating substrates for optical components with essentially radially symmetric optical coatings, the method comprising: providing no more than one material source the one material source located at a material source position; arranging at least one substrate with respect to the material source such that coating locations on a coating surface of the substrate facing the material source are coated by coating material emanating from the material source; rotating the substrate about a substrate rotation axis; controlling a radial film-thickness characteristic of the coating such that quantities of material incident on coating locations on the coating surface are adjusted depending on the radial distances of the coating locations from the substrate rotation axis; defining a limiting incidence angle that represents a maximum tolerable incidence angle; and controlling an incidence angle of the coating material by limiting the incidence angle such that the incidence angle at every coating location on the coating surface does not exceed the limiting incidence angle at any time during coating.
