Donghai Quansheng Quartz Products Co., Ltd.
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 ultravilet ray and set out maximum visible light .it serves as the material of quartz alogen 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 .
For detailed dimensional toletance and technical data please see table I,table II,table III, tableIV.
