A Fabry-Perot filter is applied as a thin coating on a film, for example, a packaging film, and permits interesting color effects. The coating has a layered construction in which both reflecting layers of the filter may be made of aluminum and the intermediate layer between the reflecting layers may be made of aluminum oxide.

A guide arrangement () for guiding webs in evacuatable web treatment installations comprises at least one guide roller () with an axis (), whose spatial position is settable. To solve the problem of compensating in modular installations with several chambers either misalignments of the chambers relative to one another and/or to avoid completely adjustable roller frames, whose adjustment would require the repositioning of treatment and coating sources and of separating gaps on the circumference of coating rollers, the invention proposes that the guide roller () is supported between two pivot bearings (), of which at least one is adjustable relative to the other transversely to the axis (). This is preferably carried out thereby that the adjustable pivot bearing () comprises a slide guide (), fastened to a chamber wall (), on which a slide () with the pivot bearing () is guided, and that the adjustable pivot bearing () comprises a remotely operated adjustment drive ().

A pure metal is vaporized in a receiver, and a quantity of oxygen slightly substoichiometric for the oxide is introduced. To determine the thickness of the layer deposited on the film and to control the vaporization rate, optical sensors are installed in an area where the layer, because of the presence of unoxidized metal, has sufficient absorption for optical measurement. After the determination of the transparency by the sensors, the layer is subjected to a secondary oxidation process.

An optical recording medium for an audio-video or ROM compact disc comprises a pitted translucent base material and a layer of a corrosion resistant metal or combination of metals from the group consisting of tantalum, chromium, cobalt, and nickel. For example, TaNi or CrCo can be applied to the surface, providing good adhesion, reflecting light, providing a printable surface, and not requiring any further coating such as a protective lacquer.

In an optical recording medium, for an audio-video or ROM compact disc comprising a pitted translucent base material and a layer (9) of a corrosion resistant metal or combination of metals from the groups 4N, 5N, 7N or 8N of the periodic table of elements is disclosed. For example NiCr can Be Applied onto the surface having the pits (7), thereby providing good adhesion, reflecting light and providing printable surface and not requiring any further coating such as a protective lacquer. Also, in the event that a gold-colored glossy layer is necessary, a CuBe layer can be sputtered onto the substrate (8).

An apparatus to apply materials to a substrate disposed in a vacuum chamber is disclosed. A separate generator chamber containing an electron emitter is connected to the vacuum chamber by a process chamber so that a plasma of controllable cross-sectional shape and large area is formed and guided by magnets toward a target system. Positive ions may be accelerated against the target by applying an adjustable negative voltage.
