A novel structure for a small, inexpensive, and easily replaced infrared source having near blackbody emission over a spectrum of 2-20 micron wavelengths is disclosed. The source element is self-starting and has a life expectancy in excess of 1000 hours at 1700 degrees K, which requires only 22 watts of power to maintain. Because the source is energy efficient, there is no need of auxilliary cooling or added thermal isolation from adjacent components when the source is used in an instrument such as a spectrophotometer.
