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 .
UV-stop quartz tube
