Filling

Mercury xenon lamps from LTI are filled with mercury and 99.999% pure xenon gas, a rare noble gas. This results in extremely high spectral output energy in the ultraviolet region. In order to ensure high performance and long lamp life, the xenon gas must meet stringent purity standards, and thus must contain virtually no impurities. The lamps are specifically designed to distribute the mercury vapor evenly; the result is increased UV output and extended lamp life.

Mercury xenon lamps are filled to a positive pressure between 0 and 10 atmospheres; this pressure rises dramatically during operation due to the increase in lamp temperature.
