UV-Blocking Quartz Tubes: Protecting Against Harmful Radiation
Our UV-blocking quartz tubes provide exceptional protection against harmful ultraviolet radiation. These Ce-doped quartz tubes effectively block nearly all UV-B and UV-C rays, as well as a significant portion of UV-A radiation — all while maintaining high visible light transmission. Ideal for halogen lamps, high-intensity discharge lamps, and other UV-emitting light sources.
Key Benefits
- Superior UV Protection: Blocks UV-B, UV-C, and a portion of UV-A rays to reduce radiation exposure.
- High Visible Light Transmission: Maintains bright light output while filtering harmful wavelengths.
- Versatile Applications: Suitable for halogen and discharge lamps, sterilizers, and scientific lighting.
- Protection for People and Objects: Prevents skin damage and shields UV-sensitive materials.
