Sell UV-stop quartz tube

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 chemiacal 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.
