This Ce doped glass tube can stop nearly all the radiation of ultraviolet ray of
UV-B&UV-C and big proportion radiation of ultraviolet ray of UV-A.It is an ideal
material which stops ultravilet ray and sets out maximum visible light .It serves
as the material of quartz halogen lamps ,high density discharge lamps and other
UV light,which prevent the harm to the skin of people and things which
have to be under the UV radiation .It sets out the maximum visible
light at the same time .
The surface of UV-stop quartz tube is clear or slight blue and its cut surface is light blue.Besides its good physical and chemical capblities as common quartz tubes have, it also can filter out wavelength between 190-320nm,which stops the radiation to the body. Because of its properties ,it can be used to produce various types of environment-friendly electric light products.
