Abstract: Examples relate to a device including an application unit having a first roller and second roller forming, in a nip thereof, a first roller gap through which powdered material can be conveyed to form a dry film. A counter-pressure roller together with the second roller, or a further roller downstream from the second roller, forms a second roller gap. A substrate path leads through the second roller gap for guiding a carrier substrate web through the second gap for applying the dry film thereto. At least one drawing device including a drive means for adjusting the first or second roller gap between two adjacent rollers that are movable relative to one another is provided on each frame side, enabling the two rollers to be moved toward one another in an adjustment direction, or be tensioned, and to be moved away from one another again, or at least be relaxed.

Abstract: Nonpolarizing beam splitter has at least one substrate, to which a partially reflective coating having a plurality of layers is applied. The layer sequence of the coating includes at least one metal layer, at least two first refractive layers made of a high or medium refractive index dielectric material, and at least two second refractive layers made of a low or medium refractive index dielectric material.
