Cerium doped quartz tube can filter ultraviolet light

The surface is colorless or slightly blue, and the section is light blue. The quartz tube infiltrated with cerium and other trace elements can effectively prevent all the radiation of UV-B and UV-C ultraviolet rays and most of the radiation of UV-A ultraviolet rays, filter the ultraviolet rays with the wavelength of 190-320nm in the ultraviolet spectrum, avoid harm to human body, and have visibility and transmission. It is used to produce environmental protection electric light source products such as quartz halogen lamp, gas discharge lamp and UV light source.
