研究室および化学用途Quartz light guide rods utilize the principle of total internal reflection for transmitting light signals. When light travels from an optically dense medium to an optically less dense medium, if the angle of incidence is greater than or equal to the critical angle, the light will be totally reflected back into the original medium, thereby achieving light transmission. Within a quartz light guide rod, light undergoes continuous total internal reflection at the inner walls of the rod, thereby traveling along the length of the rod towards the target location.

There are two primary methods for producing quartz rods: the continuous method and the flame fusion method (also known as the gas fusion method).
Continuous Method: In this method, quartz sand is fed from the top into a furnace, which comprises a metallic quartz crucible surrounded by electric heating elements. The quartz sand melts at high temperatures. The molten material then passes through a shaping orifice at the bottom of the crucible, producing rods, tubes, sheets, or other various specified product forms.
Flame Fusion Method: This method involves using hydrogen and oxygen to melt colorless quartz crystal. The molten material is formed into quartz glass through the melting and congealing of crystalline particles in the flame. The quartz glass is then removed from the flame through different methods and processed into quartz rods of the desired shape.
高温耐性
Quartz glass exhibits excellent high-temperature resistance, maintaining stability in high-temperature environments.
Low Thermal Expansion Coefficient
The thermal expansion coefficient of quartz glass is extremely low, ranging from 1/12 to 1/20 of that of ordinary glass, contributing to its stability under temperature variations.
耐食性
Quartz glass is resistant to a variety of acids, bases, and salts, with the exception of hydrofluoric acid and hot phosphoric acid above 300 degrees Celsius.
High Light Transmission Rate
The light transmission rate can reach 99.9%, ensuring high transmittance of light signals during transmission.

In laser surgery, physicians use quartz light guide rods to transmit laser beams to the treatment area, enabling precise surgical procedures.
They are also used in optical imaging systems to help physicians observe internal structures, thus improving diagnostic accuracy.
Scientific Research Field
Researchers use quartz light guide rods to set up optical experimental systems for studying optical phenomena and the properties of optical materials.
They are also used in equipment like laser interferometers and optical sensors for precision measurement and experiments.
Other Fields
In the biotechnology field, quartz light guide rods are used for fluorescence detection and analysis, allowing rapid and highly sensitive detection of biomolecules.
In laser processing, they are used for laser cutting and laser marking, characterized by high energy density, high precision, and high efficiency.
They are also used in the manufacturing of various optical instruments, such as microscopes, telescopes, and thermal imagers, transmitting light and changing its direction to achieve specific observational effects.
Quartz light guide rods exhibit excellent long-term stability in various environments. They possess a high degree of chemical stability, allowing them to maintain their performance and integrity in a wide range of chemical environments. Additionally, the thermal expansion coefficient of quartz glass is among the lowest of common industrial glasses, which means that it maintains good dimensional stability during temperature changes and is highly resistant to thermal shock.
Quartz light guide rods possess extremely high chemical stability and are nearly unreactive with most acidic and alkaline substances, except for hydrofluoric acid. This corrosion resistance makes them invaluable in environments where frequent contact with corrosive materials is common.
Quartz stirring rods offer superior high-temperature resistance and chemical stability compared to plastic stirring rods. Additionally, they possess high structural strength, are less prone to breakage, and have a long service life.

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。
