UV- stop quartz glass tube
Capable to stop nearly all the radiation of UV-B & UV-C and a big proportion of UV-A with maximum visible lights. The Ce doped quartz tube can serve as the material of halogen lamps, high density discharge lamps and other UV lamps. Thus, it effectively prevents the harm to the skin of people and objects that have to be under the explosion of UV radiation and set out the maximum visible light at the same time.
