PROPERTIES OF QUARTZ

The most important property of an optical material is the internal and external transmittance, surface reflectance, and refractive indices. Fused and synthetic silica are ideal materials for many optical and light applications where a high transmittance is required. Quartz is extremely transparent over a wide spectral range, with a low coefficient of thermal expansion and quartz is resistant to scratching and thermal shock. Synthetic fused silica is formed by chemical combination of silicon and oxygen. Fused quartz is made form crushing and melting natural materials. The purity of quartz is paramount to the efficiency of the ultraviolet  lamp and  quartz tube or sleeve. Fused and synthetic quartz ultraviolet lamps and sleeves offers the customer:

  • Greater ultraviolet light and infrared heat  transmission
  • Low coefficient of thermal expansion, providing stability and resistance to thermal shock over large temperature ranges.
  • Increased hardness and resistance to scratching
  • Higher resistance to solarisation or darkening from ultraviolet light radiation

Optical quality fused silica is ideally suited for applications where high ultraviolet radiation transmission is required. Fused silica quartz has very low fluorescence levels at 254nm and does not fluoresce in response to wavelengths longer than 290nm.
