The optical properties of fused quartz lets us choose between various types, because the degree of transparency defines material purity and the method of manufacture. Certain indicators are the UV cutoff and the presence or absence of bands at 245 nm and 2.73 um. The UV cutoff varies from 155 to 175 nm for a 10mm thick test sample. The presence of transition metallic impurities will move the UV cutoff towards longer wavelengths. The curves in the figure below represent the average transmissions for a 10mm thick test sample for both commercial and optical grades. Fused quartz is very efficient for the transmission of infrared radiation. Infrared transmission extends out approximately 4 micrometers, with little absorption in the “water band” at 2.73 um.
