Product Description

General Introduction: It is a high purity synthetic amorphous silicon dioxide manufactured by flame hydrolysis. The noncrystalline, colorless, silica glass combines a very low thermal expansion coefficient with excellent optical qualities and exceptional transmittance in the deep ultraviolet. ArF Grade was developed for 193 nm lithography systems.
In order to satisfy the challenging quality requirements of our customers in leading edge applications such as microlithography, the manufacturer is dedicated to continuous improvement. Our investments in research and develop- ment, combined with Usa fused silica quality systems, support our technology leadership position and ensure that we meet our customer's requirements on time, every time.
Ultra pure fused silica glass material HPFS 7980
Materials were first developed by the manufacturerfor US aerospace equipment, and then gradually used in commercial field. The fused silica has made a comparison between Schott's and Russia's corresponding materials. The products have obvious advantages in uniformity and consistency. The most important thing is that this fused silica products have very small and stable material stress in the case of similar optical and mechanical properties.
