Quartz raw materials and the oxyhydrogen flame producing quartz glass, several tens of ppm of metal-containing impurities. Absorption peak (hydroxyl content 100-200ppm) at 2730nm at streaks and particle structure. It is through the wavelength range within 220-2500m good material.
It is a high-purity silicon tetrachloride synthetic optical quartz glass containing a large amount of hydroxyl (2000ppm). It has excellent UV properties of the lens, particularly in the short-wave UV region, which far better than all the other transmission properties of glass, at a transmittance of 90% 185�¼m, synthetic quartz glass has a strong absorption peak at 2730nm at no granular structure. Is an excellent optical materials within 185-2500m�¼ band range.
Fused quartz materials and vacuum production of quartz glass, several tens of ppm of metal-containing impurities. Small bubbles, particles and striped structure, almost no (OH), with higher performance through the infrared transmittance over 85%, and its applications in the wavelength range of 260-3500m optical material.
Fused silica has high working and melting temperatures and it differs from traditional glasses in containing no other ingredients than silica in amorphous. The optical and thermal properties of fused quartz are superior to those of other types of glass due to its purity. It has better ultraviolet transmission than most other glasses, and so is used to make lenses and other optics for the ultraviolet spectrum.
Small thermal expansion coefficient, good chemical stability, bubbles, stripes, homogeneity, birefringence makes it very proper material for optical fiber base product.
Mainly Applied: special light source, optics, optoelectronics, military industry, metallurgy, semiconductors, optical communications and other fields.
