Device and a method for curing patterns of a substance at a surface of a foil

摘要

A device is described for curing patterns of a substance at a surface of a foil. The device a carrier facility for carrying the foil within an object plane, a photon radiation source arranged at a first side of the object plane for emitting photon radiation in a wavelength range for which the foil is transparent, and a first and a second concave reflective surface arranged at mutually opposite sides of the object plane for mapping photon radiation emitted by the photon radiation source into the object plane. Therein the photon radiation source is arranged between the first concave reflecting surface and the object-plane. The photon radiation of the photon radiation source is concentrated into the object plane by the first and the second concave reflective surface.
