Neon is used in specialty lighting applications.
Neon is a major component excimer laser mixes and mixtures used in photolithography process used in semiconductor manufacturing.
It is used in glow lamps, fluorescent lamps, and plasma displays. It is especially useful in lighting systems that are used in cold areas.
Neon is used as both a buffer gas and active medium in lasers. It is used in types of gas lasers including ion lasers, excimer lasers and in helium-neon lasers. Helium neon lasers are used in a variety of commercial applications including in bar code scanners.
With a boiling point of -410.94°F (-246.08°C) liquid neon can be used as a cryogenic refrigerant. It has over forty times the refrigerating capacity by volume as helium.
Neon also finds application in a number of research areas. It is a component in some lung diffusion mixtures, to test pulmonary function. Neon mixtures are also used to calibrate analytical instruments that measure the amount of carbon monoxide diffused through the lungs. Neon is used as a carrier gas in specialty chromatography applications.
It is used as a filling gas in spark chamber particle detectors, Geiger tubes and other detectors, fluorescent lamps, sodium discharge lamps, digital display tubes, stroboscope lights, in signs in mixtures with argon, filament lamps, and telephone line surge arrestors.
