What is a Vacuum Ultra Violet Light Source?

It is the portion of the UV spectrum that requires air to be removed before it can be detected it’s called Vacuum UV or VUV.

 

What are VUV Light Sources used for?

Such sources are used for testing materials since the high energy of the photons results in chemical activity on surfaces. They are used as stimulators of solar light at short wavelengths by people studying solar VUV damage of spacecraft materials. They are used for simulating chemical reactions in gases. They are used to treat or clean surfaces for chip manufacturing. They are used to selectively excite gases for isotope dating. They have been used in biological studies. They have been used to measure atomic species on the border of space (300 km). They have been used to measure the gases in rocket engines and ion plasma space drives. There are a variety of applications covering fields from biochemistry to space astronomy.
