Abstract
A high output, narrow band thermally energized radiation source comprises a rare earth oxide radiator member that has a cross-sectional dimension in the range of five to thirty micrometers, the rare earth oxide radiator member, when heated to about 1700.degree. C., having a concentrated radiated flux over the 400-2500 nanometer wavelength range such that at least 50% of the radiated flux is within a spectral band that is less than 400 nanometers wide.
