UV
Blocking TubingThis is clear fused quartz glass doped with cerium to block ultraviolet. This glass block all vacuum ultraviolet, nearly all UV-C, UV-B and emit minimum UV-A. It is an ideal material for lamps requiring maximum visible light and to avoid UV exposure to people and materials.
This glass can be supplied in the range between 6mm-60mm outside diameter.
Application:
Now days, more and more cars are using plastic front windows. The plastic
front windows may be discolored under the exposure of deep ultraviolet.
The automobile lamps made by UV Block quartz glass tube can stop
deep UV exposure to plastic windows to keep the windows out of becoming
“yellow”discoloration and emit super “white” visible light at the
same time. So it is ideal for automobile lamps.
As for light, the shorter the wavelength, the big the
energy. The wavelength of Vacuum UV, UV-C, UV-B are shorter, so they have
bigger energy. UV-C can do great damage to exposed cells. UV-B are
hazardous and are largely responsible for sunburn. UV-B is also largely
blamed for a kind of deadliest skin cancer "malignant
melanomas". This quartz tubing can block nearly all short UV
wavelength which is an ideal material to make lamps for UV protection
purposes.
Application is as follows:
| OH | Application |
| OH<50PPM | automobile lamps, halogen lamps for GLS, MH lamps, sleeve tube for MH lamps. |
