FUSED QUARTZ/FUSED SILICA AVERAGE TRANSMITTANCE CURVES
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 2.73µm.
