アプリケーション・シナリオ
Vacuum Equipment
Quartz Square Windows are commonly used in vacuum equipment as observation windows to monitor internal production conditions within vacuum chambers, such as temperature, sample status, or to transmit light sources to monitor internal processes.
Optical Instruments
In the optical field, Quartz Square Windows are used to fabricate optical window plates, microscope lenses, and other components due to their high transmittance, low dispersion, and low birefringence, providing clear and accurate viewing for scientific research.
Scientific Research
Laboratory equipment such as sample holders, containers, and reactors are often made using quartz glass to ensure the accuracy and reliability of experiments.
Medical Field
In the biomedical field, quartz glass is widely used in high-end optical devices such as optical microscopes and Raman spectrometers, supporting biomedical research.
Quartz Square Windows are crucial in vacuum equipment because they provide a transparent window for observing internal processes while maintaining a vacuum seal. The high heat resistance and chemical stability of quartz glass allow it to withstand the extreme conditions of vacuum environments, while its high transparency ensures clarity of observation.
Quartz Square Windows exhibit superior heat resistance, able to withstand continuous use temperatures of up to 1100°C and short-term temperatures of up to 1450°C. This makes them highly suitable for applications that require observing high-temperature processes, such as high-temperature furnaces and chemical reactors.
The applications of Quartz Square Windows in optical instruments include their use as window plates in microscopes, entrance and exit windows in spectrometers, and other optical components requiring high light transmission and low dispersion. The superior optical properties of quartz glass make it an ideal material choice for these applications.

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。
