Product Description

General Introduction: The VAD-process synthetic fused silica CFS-100 as a result of significant improvements made to the conventional VAD(Vapor-phase axial deposition) method of optica fiber manufacturing technology.
Quartz is extremely high in purity and much lower in OH content than the traditional direct method, thus making it the first synthetic fused silica usable in the semiconductor and liquid crystal display industries.
It is the state-of-art technology in optical characteristics because it provides a high ultraviolet transmission, no micro inclusion and a solarization resistance, in addition to heat resistance, mechanical strength, and chemical resistance.
