Patent ID: 8395135

Claim:
A device for curing patterns of a substance at a surface of a foil comprising 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, 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, the photon radiation source being arranged between the first concave reflecting surface and the object-plane, characterized in that the photon radiation of the photon radiation source is concentrated into the object plane by the first and the second concave reflective surface wherein the photon radiation source is a tubular radiator with a length-axis and the first and the second reflecting surfaces are cylindrical surfaces extending along the length axis, and wherein the first and the second concave reflective surface each have a first and a second focal line, wherein the second focal lines of the first and the second concave reflective surfaces at least substantially coincide with each other in the object-plane, and wherein the tubular radiator at least substantially coincides with the first focal line of one of the first and the second concave reflective surfaces.
