SELECTIVE ELECTROMAGNETIC WAVELENGTH CONVERSION DEVICE

摘要

A method and apparatus for increasing the output of an infrared emitter (10). High temperature concerns affecting the radiant energy transfer efficiency of the infrared emitter (10) are addressed by varying the emitter tube design and varying the locations of both the reflective (110) and high (220) emissivity materials located on the emitter constituent parts. A cooling fluid may be passed through the emitter (10) from both ends to allow higher power density or to cool the emitter (10) during its operation. Selectable wavelength infrared emissions are achieved through the design of the infrared emitter (10).
