A method and an apparatus for preparing a top coat layer

In a method for producing a top coat layer on at least a substrate by vaporizing a Topcoatmaterials in a vacuum chamber, which has an evaporation container for vaporizing the Topcoatmaterials, it is provided that at least one substrate is moved about an axis during the evaporation, which has a relative to a main direction of evaporation angle has greater than 0 ° to 90 ° in a region. It is further contemplated that the top coat layer is applied to a built-in a frame lens. In the apparatus, a substrate holder is provided which is used during the evaporation of at least one substrate is movable about an axis, having, relative to a main evaporation direction an angle in a range greater than 0 ° to 90 ° and / or a holder for at least one frame, in that a lens is at least mountable.
