UV Blocking Tubing

This is clear fused quartz glass doped with cerium to block ultraviolet. This glass blocks 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.
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 from "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 bigger the energy. The wavelengths 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 wavelengths are hazardous and are largely responsible for sunburn. UV-B is also largely blamed for a kind of deadly skin cancer called "malignant melanoma". 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<50PPM Automobile lamps, halogen lamps for GLS, MH lamps, sleeve tube for MH lamps.
