A system for direct injection of selected, narrow bandwidth thermal-infrared (IR) radiation or energy into articles for a wide range of processing purposes is provided. The irradiation wavelengths are selected according to the specific absorption band characteristics of the target entity to create the desired efficiency of thermal transfer. The applications of the invention may include heating, raising or maintaining the temperature of articles, or stimulating a target item in a range of different industrial, medical, consumer, or commercial circumstances. The system is especially applicable to operations that require or benefit from the ability to irradiate at specifically selected mid-infrared wavelengths or to pulse or inject the radiation. The system is particularly advantageous when functioning at higher speeds and in a non-contact environment with the target. |
