Product Detail
UV Stop Quartz Glass Tube
This quartz tube is an ideal material which stops ultraviolet ray and set out maxi-mum 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 vis-ible light at the same time.
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 maxi-mum 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 vis-ible light at the same time.
The surface is transparent colorlesslight or slight blue, cutting section is ligh blue.
