Product Description RAYTEK Fused Silica Glass: Ultra-Pure Material for High-Precision ApplicationsProduct Description In the field of high-end functional materials, Raytek Fused Silica Glass stands out as a core component for precision industries worldwide, thanks to its extreme purity and exceptional performance. As an ultra-pure amorphous glass, it is manufactured from high-purity silica, with a silica concentration exceeding 99.99% - far above industry standards - and only trace amounts of other metal oxide impurities. This rigorous purity standard not only differentiates it from ordinary glass but also lays a solid foundation for its reliable use in high-demand scenarios General Introduction: Fused silica glassRaytek fused silica is an ultra-pure, amorphous form of glass that is made from high purity silica. Typically, the concentration of silica is greater than 99.9999% with miniscule quantities of other metal oxides. Due to its extremely high purity, it finds many applications in optical windows, optical components for UV transmission, IR optics (with OH- ions removed), semiconductors, metrology and more. Raytek is committed to providing high quality fused quartz. According to the content of hydroxyl (OH), fused quartz can be divided into high hydroxyl, medium hydroxyl and low hydroxyl.The characteristics of fused silica products include: extremely low refractive index change, resulting in the highest level of homogeneity; The birefringence is very low; Large size; Excellent transmittance from UV to IR; And ultra-low coefficient of thermal expansion; All of these features are critical to meeting the demanding requirements of customers. Our AdvantagesProducts Name: Fused silica glassAlias: Fused silica glass, Fused silica, C-laser fused silica, quartz glass, quartz, Corning fused silica, Ohara fused silica, Schott fused silica, optical fused silica, optical quartz, optical fused silica glass, optical quartz glass, etcRaytek Fused Silica Glass is engineered to meet the most demanding precision standards, with key features including:Ultra-Low Refractive Index Variation: Ensures industry-leading homogeneity, eliminating optical deviations caused by uneven refractive index. Critical for high-precision optical components (e.g., lenses, prisms) to maintain imaging quality and light transmission efficiency.Extremely Low Birefringence: Enhances optical stability, making it perfect for precision optical equipment sensitive to polarization - such as laser systems, high-end microscopes, and optical communication devices.Large-Size Capability: Overcomes the size limitations of traditional glass, enabling the production of large-format components. Meets the needs of semiconductor wafer carriers, aerospace optical windows, and other large-scale precision parts.Broad Spectral Transmittance: Delivers excellent transmittance from the ultraviolet (UV) to infrared (IR) bands. In the UV range, it enables efficient UV transmission for UV lithography and UV detection; in the IR range, low-OH variants ensure clear IR signal transmission.Ultra-Low Thermal Expansion Coefficient: Maintains dimensional stability even under extreme temperature fluctuations. Prevents deformation or damage caused by thermal expansion/contraction, ensuring long-term precision in semiconductor high-temperature processes and aerospace extreme environments.
