This Ce doped glass 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 ultraviolet ray and set out maximum visible light.It serves as the material of quartz halgon lamps,high density discharge lamps and other UV light,wich prevent the harm to the skin of the people and the things which has to be under the exposion of UV radiation and set out the maximum visible light at the same time.

UV blocking quartz tube OD range 2.2mm to 80mm,UV-1 blocking quartz tube ,clear or slight blue,cutsurface light blue.The UV1 virtually blocks the UVwavelenghth between 190 to 320mm,while still has the high tranmittance in visible wac\velenghth.UV1is widely used in many kinds of Human-friendly.
