高温耐性
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.
アプリケーション・シナリオ
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.

よくある質問
石英ガラスは硬くて脆い材料で、物理的、化学的性質が優れ、機械的硬度が非常に高く、電気絶縁性がよく、高温と耐食性に優れ、遅延性能が低く安定で、光透過性がよい。半導体、光学、電気、化学、航空宇宙、自動車などの分野で広く使用されている。硬くて脆い材料は加工が難しく、多くの分野で刃先の倒れが小さく、材料ロスが少なく、断面粗さが小さく、切断厚さ範囲が広い切断加工が急務となっている。石英ガラスの伝統的な切断方法は機械的切断、すなわち砥石切断である。非伝統的な切断方法には、ウォータージェット切断、電気化学放電ワイヤー切断、連続レーザー切断などがある。機械的切断はコストが低いが、ホイールと材料が接触するため工具の摩耗が大きく、材料が工具によって汚染されやすい。石英ガラスはエッジ崩壊、マイクロクラック、残留応力が発生しやすく、材料の強度や性能に影響する！曲線切断が難しく、研削や研磨などの後処理が必要。レーザー切断は材料に直接触れないため、接触応力がなく、複雑な曲線切断が可能です。ピコ秒レーザーは、スポット径が小さい、精度が高い、材料との作用時間が短い、作用面積が小さいなどの利点があり、硬くて脆い材料の加工に適しています。
