<p>A source of infrared radiation is provided which includes a thin film resistive heater of high emissivity evaporated onto a substrate. The thin film heater is positioned between a pair of thin metal elements on the substrate. The resulting structure provides a well-defined, mechanically stable source. In one embodiment of the invention, the resistive element is coated with an antireflecting layer to enhance its emissivity.</p> |
