Critical to the efficient transmission of light, clear fused quartz contains very low levels of impurities (as measured in parts per million). This single component glass is further distinguished from other glass material by a very high transmission of ultra violet light. The higher the purity of the material, the higher the transmittance in UV-range. For this reason, synthetically manufactured fused quartz materials show the highest transmission for ultraviolet light.
The UV transmission properties of fused quartz can be modified by the incorporation of a dopant in the material. The doping causes the material to absorb a certain range of wavelengths.
Hydroxyl (OH- ) groups in the material may cause absorption bands in infrared range. The strongest of these bands, at 2,73 μm is used to determinate the OH-content in fused quartz materials. The higher the OH-content, the higher the absorption at this wavelength.
The light transmission of fused quartz may be reduced or even extinguished when the material is exposed to high-energy UV-radiation, X-rays, gamma rays and particle bombardment.
Mechanical Properties (at 20°C)
Mechanical property measurements are dependent upon geometry, thermal gradient and surface quality. For proper strength calculations, the lower pressure variable should be used.
