Application
Quartz materials for semiconductor and optical industries ( LCD optical mask substrate, lens and mirror, aerospace window, large aperture reflection grating)
Product Feature
The synthetic quartz ingot is made with synthetic material by hydrogen and oxygen flame melting method.
Product feature is extremely high purity (total impurity content less than 0.2 PPM), high UV transmittance (internal transmittance of 185nm reaches over 92%), limiting bubble level and low stress.
