    Description

    General Introduction: Corning 7979 are high purity, noncrystalline silica glasses that combine a very low thermal expansion coefficient with excellent optical qualities and exceptional transmittance. Characteristics include homogeneity, low birefringence and outstanding transmittance in the DUV, UV, visible, and infrared ranges.
    Corning HPFS Fused Silica glasses are known throughout the industry for their consistent, repeatable performance. We offer many different grades of fused silica to support various product applications. Glass codes 7979 is high purity non-crystalline silica glasses with excellent optical qualities. Product characteristics include extraordinarily low refractive index variations leading to state-of-the-art homogeneity values, low birefringence values, large size capabilities, exceptional transmittance from the deep ultraviolet through the infrared region, and an ultra-low thermal expansion coefficient; all of which are critical to our customers demanding needs
