  • Product Code: UV-STOP QUARTZ GLASS TUBE
  • Availability: In Stock
This Ce doped glass can stop nearly all the radiation ultraviolet ray of UV-A&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 halogen lamps,high density discharge lamps and other UV light,which 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
The detailed dimensional tolerance and technical data can be found in table.
