A doped quartz material that blocks most UV-B and UV-C radiation. GE 254 has a transmittance cut off wavelength between 350 and 400 nanometers. It is ideal for lamps requiring maximum visible transmittance with nearly complete UV protection. Applications for GE 254 are those where UV exposure to people or property is undesirable, including some quartz halogen and metal halide lamps and other UV sources.
UV blocking cerium doped clear fused quartz which absorbs essentially all UV-B and UV-C radiation while maintaining transmittance efficiency in the visible spectrum range.
UV-sensitive high temperature applications including halogen and discharge lamps where UV radiation would create personal or material exposure risks. Eliminates need for coatings, filters, and lenses for UV blocking.
