Resistencia a altas temperaturas
Quartz custom windows can withstand extremely high temperatures, with a softening point around 1730°C. They can be used continuously at 1100°C and can tolerate short-term temperatures up to 1450°C.
Chemical Stability
Except for hydrofluoric acid, quartz custom windows are highly resistant to chemical reactions with almost all acids, exhibiting exceptional chemical stability.
Thermal Stability
Quartz custom windows have a very low thermal expansion coefficient, enabling them to withstand dramatic temperature changes. They can endure large temperature differences repeatedly within a short period without cracking.
Optical Performance
Quartz custom windows exhibit good light transmission across the entire spectrum from ultraviolet to infrared. They have a visible light transmission rate above 93%, with higher transmission rates, up to 80% or more, particularly in the ultraviolet range.
Escenario de aplicación
Optical and Light Source Industries
Quartz custom windows, due to their high heat resistance, corrosion resistance, and low thermal expansion, are widely used in the optical field for manufacturing telescope lenses, laboratory optical equipment, communication devices, diffractive lenses, projection displays, scanning equipment, printer optical components, and also in cameras and ultra-flat television screens.
Aerospace Industry
Quartz glass fibers and composite materials based on quartz glass fibers, due to their high heat resistance, ablation resistance, high wave transmission, and electrical insulation properties, are widely used in aerospace and marine equipment.
Optical Fiber Communication Industry
Quartz glass is a primary raw material for optical fibers, and its high purity ensures the signal quality of optical fibers. Quartz glass is extensively used in the production of optical fiber rods and drawing processes, guaranteeing high performance and stability of optical fibers.
Photovoltaic Industry
In the photovoltaic field, quartz glass is used as a rigid consumable material in photovoltaic modules, greatly increasing photoelectric conversion efficiency. Quartz crucibles made from quartz glass are used as containers for melting polycrystalline silicon, for the subsequent process of pulling single-crystal silicon rods or multi-crystal silicon ingots.
The primary material of quartz custom windows is high-purity quartz glass, which possesses unique physical properties including extremely high-temperature resistance (capable of continuous use at 1100°C and short-term exposure up to 1450°C), excellent optical transmission (particularly in the ultraviolet range), an extremely low thermal expansion coefficient, and outstanding chemical stability. These characteristics make them highly desirable in a variety of industrial applications.
Quartz custom windows exhibit exceptionally high resistance to most chemicals, except for hydrofluoric acid and hot phosphoric acid. This makes them highly suitable for chemical laboratories, chemical production, and other applications where corrosion-resistant viewports are required.
The advantages of quartz custom windows in optical applications stem from their high transparency and broad spectral transmission, enabling excellent light transmission across the entire spectrum from ultraviolet to infrared. This feature is critical for applications requiring high clarity and precise control of light, such as in high-end optical instruments, optical fiber communication, and research equipment.

Preguntas más frecuentes
El vidrio de cuarzo es un material duro y quebradizo con excelentes propiedades físicas y químicas, dureza mecánica extremadamente alta, buen aislamiento eléctrico, resistencia a altas temperaturas y a la corrosión, rendimiento de retardo bajo y estable, buena transmitancia luminosa, etc. Se utiliza ampliamente en semiconductores, óptica, electricidad, química, aeroespacial, automoción y otros campos. Los materiales duros y quebradizos son difíciles de procesar, y muchos campos necesitan urgentemente procesos de corte con un pequeño colapso del borde, menos pérdida de material, baja rugosidad de la sección transversal y un amplio rango de grosor de corte. El método de corte tradicional del vidrio de cuarzo es el corte mecánico, es decir, el corte por disco. Los métodos de corte no tradicionales incluyen el corte por chorro de agua, el corte por hilo de descarga electroquímica, el corte por láser continuo, etc. El corte mecánico tiene un bajo coste, pero el contacto entre la rueda y el material causa un gran desgaste de la herramienta, y el material es fácilmente contaminado por la herramienta. El vidrio de cuarzo es propenso al colapso de los bordes, las microfisuras y la tensión residual, lo que afecta a la resistencia y el rendimiento del material. Es difícil conseguir un corte curvo y requiere un tratamiento posterior, como esmerilado y pulido. El corte por láser no entra en contacto directo con el material, no tiene tensión de contacto y puede realizar cortes curvos complejos. El láser de picosegundos tiene las ventajas de un diámetro de punto pequeño, alta precisión, tiempo de acción corto con el material y área de acción pequeña, y es adecuado para el procesamiento de materiales duros y quebradizos.
