摘要： Treating of a workpiece (W) which frequently undergoes heat-induced changes such as deformation, color changes and the like without using a cooling means for the workpiece (W) is achieved by the fact that, of the light which was incident from a rod-shaped lamp (1) on a trough-shaped cold mirror (2), the ultraviolet light (including some of the visible rays and infrared light) is reflected by the trough-shaped cold mirror (2) and by at least one other cold mirror (4,4',5) which is preferably plate-shaped. Furthermore, of the light which was emitted from the rod-shaped lamp (1) and which was incident on the other cold mirror(s) (2,4,4',5), the ultraviolet light (including some of the visible rays and infrared light) is reflected by the other cold mirror(s) (2,4,4',5). The light reflected by the other cold mirror(s) (2,4,4',5) is incident on the plate-shaped heat refraction filter (3) and some of the visible rays are reflected and are incident on a workpiece (W). The light emitted by the rod-shaped lamp (1) is not directly radiated onto the workpiece (W) via the heat refraction filter (3). Therefore, the IR component and the component of the visible rays which are emitted onto the workpiece (W) can be reduced and overheating of the workpiece (W) can be prevented.
