Neon (Ne, from Greek “neos” – new, novel) is the second rare gas after Helium, neither flammable nor toxic, and forms a coloress, odorless, monoatomic and chemically inert gas. With the Neon gas molar mass being 20.18 g/mol, corresponding to a Neon density of 0.842 kg/m3 at 15 °C / 1000 mbar, it is lighter than air. However, in Earth’s atmosphere this effect is rather insignificant, as Neon is found only in traces of 18.2 ppm (18.2 parts per million, roughly 1 out of 50.000 particles).

Main application of neon is a laser-based lithography process in chip manufacturing. The laser carves patterns onto silicon, which finally become circuits on microchips. In addition, excimer lasers are used to manufacture high-resolution smartphone displays, tablets or VR headsets.  Excimer lasers are not limited to electronics applications, however. They are also deployed in the medical industry.  For example, they are used in medical treatments like operations on corneas to correct eyesight and in the treatment of skin diseases (e.g. vitiligo).

In addition to pure neon, we offer a comprehensive portfolio of neon gas mixtures for excimer lasers. Available in a variety of purities and concentrations, the compressed products are filled into cylinders which are available in all standard sizes and with standard connections. Our long-term expertise in producing laser gases translates into consistent gas mixture quality and stable laser performance. We also combine neon with other noble gases, halogen gases as well as flammable and toxic compounds - in the precise grades and volumes you need for your individual application.
