Fused silica Sapphire Optical Window

Product Description

The width of the solid solution region is almost temperature-independent. The comparison of the absorp-tion spectra of blue ennobled and natural sapphires  testifies to the coin-cidence of the absorption band maxima for these two objects.Ennobled blue sapphires have a faint pinkish hue typical of natural sapphires from Sri Lanka due to the presence of a narrow resonance R -line in the spectrum. Such a peculiarity is inherent in crystals with an optical density lower than 1–1.5 cm −1 in the absorption maximum. 

Although there are lots substrates which are regarded as potential materials to replace sapphire substrate, it is still dominated in the substrates (for GaN LED growth) market, because of its reasonable price and relatively low mismatch. Zhongju is capable of processing substrates according to customer needs. Currently, our sapphire substrate productions ranges from 2 to 12 inches with high quality and accurate orientation.
