Abstract
A tungsten-halogen electromagnetic radiation source has a sealed transparent aluminum oxynitride envelope defining an interior volume. At least one optical element is integrally formed into the aluminum oxynitride envelope. A tungsten filament is located in the aluminum oxynitride envelope. A fill gas in the interior volume contains at least a gaseous halogen compound.
