Clear Fused Quartz Tubing
This widely used quartz lamp tubing is a kind of clear electrically fused machine-drawn tubing. It has characteristics of excellent visual, thermal, mechanical properties with tight dimensional tolerances.
The spectral transmission from wavelength about 180-220nm usually reflects material purity for clear fused quartz. The presence of some metallic impurities will make the transmission decrease from wavelength about 180-220nm. As transmission curve illustrate, due to the presence of the higher content of some metallic impurities such as Fe etc., the transmission from wavelength 185-220nm which encourages the ozone generation is much lower. So this material can not be used for making ozone generation lamps.
