Abstract: A short-arc discharge lamp capable of reducing the likelihood of cracks starting at an end face of a reflection mirror neck unit. Such cracks can be caused by heat generated from the discharge lamp. The short-arc discharge lamp includes a glass reflection mirror having a reflection surface of an even-order function on an inner surface thereof and formed by embossing. The short-arc discharge lamp is arranged with respect to an optical axis of the reflection mirror. A base of the discharge lamp is fixed to an insertion hole in a hollow neck unit formed in a bottom center of the reflection mirror. Furthermore, a base peripheral portion on the inner surface of the insertion hole in the hollow neck unit has a cylindrical shape with a narrow portion formed to extend from the cylindrical shape toward the reflection surface. Finally, an embossed portion extends from the narrow portion toward the reflection surface while diverging to contact the reflection surface.

Abstract: A system for generating infrared light includes a sealed housing and a noble gas filling the housing. A window disposed in a wall of the housing is transparent to infrared radiation. Two electrodes, disposed in the housing, are aligned along a common longitudinal axis adapted to be approximately perpendicular to a local force of gravity. A gap is defined between the electrodes along the longitudinal axis. Obstruction(s), disposed in the housing adjacent to the gap between the electrodes, extend along the length of the gap. The obstruction(s) define a convection space between the electrodes. The convection space has a dimension, measured perpendicular to the longitudinal axis, in the range of 2 to 10 times the length of the gap. An electric current source is coupled to the electrodes.
