Quartz Wafer
Quartz wafers are widely used optical material, known for their high purity, low thermal expansion coefficient, high tensile strength, desirable light transmission, and unique electrical properties. Therefore, quartz wafers are extensively used in various fields such as PLC planar waveguide splitter chips, MEMS, and high-tech semiconductors. Our company specializes in the long-term production of high-precision quartz wafers with a thickness of ≥0.1mm and outer dimensions of ≥Φ2"". In addition to the conventional Φ4-inch, Φ5-inch, Φ6-inch, Φ8-inch, and Φ12-inch sizes, we also offer customized services for other sizes. Quartz wafers are typically made of materials from Corning, Nikon, Heraeus, etc. For custom quartz wafers made of other materials, please contact our sales. Due to their desirable optical performance, quartz wafers are also widely used in optical and photonics applications. They exhibit high transparency in the ultraviolet, visible, and near-infrared spectra, making them suitable for lenses, windows, prisms, and other optical components used in laser, spectroscopy, and imaging systems. Quartz wafers show minimal optical absorption and scattering, enabling efficient light transmission. Additionally, their low thermal expansion coefficient ensures optical stability over a wide temperature range, making them an ideal choice for demanding optical applications.
