\"C\u1eedaFused Quartz Windows are precision optical components manufactured from high-purity fused silica. They offer exceptional optical transparency, outstanding thermal stability, and strong resistance to chemical corrosion. These optical windows are widely used as protective barriers or transmission interfaces in semiconductor equipment, laser systems, vacuum chambers, and scientific instruments.<\/p>\n

With excellent transmission from ultraviolet (UV) to infrared (IR) wavelengths, fused quartz windows maintain stable optical performance even under extreme temperatures and harsh chemical environments.<\/p>\n

Advantages of Fused Quartz Windows\"C\u1eeda<\/h1>\n

Compared with ordinary glass or borosilicate windows, fused quartz windows offer:<\/p>\n

    \n
  • \n

    Higher UV transparency<\/p>\n<\/li>\n

  • \n

    Better thermal shock resistance<\/p>\n<\/li>\n

  • \n

    Lower optical distortion<\/p>\n<\/li>\n

  • \n

    Greater chemical durability<\/p>\n<\/li>\n<\/ul>\n

    These advantages make them the preferred optical solution for high-precision instruments, semiconductor equipment, and laser systems.<\/p>\n

    C\u00e2u h\u1ecfi th\u01b0\u1eddng g\u1eb7p<\/h1>\n

    Q1: What is the difference between JGS1, JGS2, and JGS3 fused quartz?<\/h3>\n

    JGS1<\/strong> is synthetic UV-grade fused silica with excellent transmission below 260 nm.
    JGS2<\/strong> is optical-grade fused silica with strong transmission in the visible spectrum.
    JGS3<\/strong> is infrared-grade material commonly used for IR and industrial optical applications.<\/p>\n

    Q2: Can fused quartz windows be used in vacuum environments?<\/h3>\n

    Yes. Due to their low outgassing rate and high mechanical strength, fused quartz windows are widely used as vacuum chamber viewports in semiconductor and research equipment.<\/p>\n

    Q3: Are optical coatings available?<\/h3>\n

    Yes. Anti-reflective (AR), high-reflective (HR), dielectric, and DLC coatings can be applied based on specific wavelength requirements.<\/p>\n

    Q4: Can custom shapes or holes be manufactured?<\/h3>\n

    Yes. Custom shapes, edge bevels, slots, and precision drilled holes can be produced according to customer drawings or technical specifications.<\/p>","protected":false},"excerpt":{"rendered":"
