UV-Blocking Fused Quartz Tubing
Type 360 fused quartz tubing is a doped quartz material that blocks UV-B and UV-C radiation. With a transmittance cutoff wavelength between 320 and 380 nanometers, type360 is ideal for lamps requiring maximum visible transmission with nearly complete UV protection. Applications for type 360 are those where UV exposure to or property is undesirable, including metal halide lamps and other UV sources.
