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, developed by OHARA,Japan.OHARA CFS-1300 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.OHARA CFS-100 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.Products Name: OHARA SK-1300 Fused Silica GlassAlias:OHARA SK-1300 glass, Ohara sk-1300 fused silica, Ohara Sk-1300, Ohara sk-1300 VAD fused silica, Ohara SK-1300 synthetic fused silica, Ohara SK-1300 optical glass, etcChemical Resistance:
