Fused Quartz Windows are precision optical components made from high-purity fused silica, engineered for superior optical clarity, high thermal stability, and exceptional resistance to chemical corrosion. These transparent discs serve as protective barriers or optical transmission interfaces in demanding scientific, industrial, and semiconductor environments. With excellent transmittance across a wide spectral range from ultraviolet (UV) to infrared (IR), fused quartz windows ensure reliable optical performance under extreme temperature and pressure conditions.
Wide Spectral Transmission: Outstanding light transmittance from 190 nm to 2500 nm, suitable for UV, visible, and IR optical systems.
High Thermal Stability: Can withstand temperatures exceeding 1000 °C without deformation, making them ideal for high-power laser and vacuum applications.
Exceptional Surface Quality: Available with precision polishing (up to 10–5 scratch-dig and λ/10 flatness) to minimize optical distortion.
Chemical Resistance: Fused quartz is inert to most acids, alkalis, and solvents, ensuring long service life even in corrosive environments.
Low Thermal Expansion: Excellent dimensional stability under rapid temperature changes, ensuring consistent optical alignment.
Optical Instrumentation: Used in spectrophotometers, imaging systems, and optical sensors.
Semiconductor Industry: Serves as viewports, process chamber windows, and wafer inspection covers in CVD, PVD, and plasma etching systems.
Laser and Photonics: Suitable for high-energy laser windows, beam splitters, and protective optics.
Scientific Research: Widely applied in vacuum chambers, laboratory optics, and analytical instruments requiring precise optical transparency.

Compared to ordinary glass or borosilicate windows, fused quartz windows provide higher UV transparency, superior heat resistance, and minimal optical distortion. They are the preferred choice for precision optical systems and vacuum equipment where reliability and purity are essential.
Q1: What is the difference between JGS1, JGS2, and JGS3 fused quartz?
A1: JGS1 is UV-grade synthetic fused silica with high transmittance below 260 nm; JGS2 is optical-grade with excellent visible transmission; JGS3 is infrared-grade with good performance above 260 nm, typically used in IR and industrial optics.
Q2: Can quartz windows be used under vacuum or high-pressure conditions?
A2: Yes. Due to their low outgassing rate and high mechanical strength, fused quartz windows are widely used as vacuum chamber viewports or high-pressure inspection windows.
Q3: Are anti-reflective coatings available?
A3: Yes. AR coatings can be customized for UV, visible, or IR wavelengths to enhance transmission and minimize reflection losses.
Q4: Can I order customized shapes or drilled holes?
A4: Absolutely. Non-standard geometries, edge bevels, and precision through-holes can be fabricated according to your drawing or specification.
