Description
SQ Fused Silica is a premium material specifically engineered for the production of optical and photonic devices, making it an ideal choice for industries such as fiber optics, semiconductors, and display technology. This high-purity material stands out due to its exceptional optical and physical properties. Its inclusion- and bubble-free nature ensures superior performance, particularly in applications requiring laser durability, refractive index homogeneity, and thermal stability. Moreover, its low stress birefringence and minimal thermal expansion coefficients contribute to its reliability in demanding environments.
The unique composition of SQ Fused Silica, characterized by high OH and H₂ content, results in extremely low fluorescence and remarkable stability under high-energy UV and laser radiation. This makes it an excellent choice for applications that involve intense light exposure, ensuring longevity and consistent performance. The material's ability to maintain its properties under extreme conditions is a testament to its quality and engineering precision.
Available in five distinct quality grades, SQ Fused Silica caters to a wide range of customer requirements. LEONI offers this material as ingots or semifinished products, such as round discs, rods, plates, and blocks. These quality grades are meticulously tailored to meet specific needs, ensuring optimal performance across various optical applications from DUV to NIR. The SQ0 grade, for instance, is ideal for optical elements requiring multiple light directions, while the SQ1 grade serves well in applications like lenses and wafers. For technical applications, the SQT grade provides a reliable solution without specific homogeneity or striae specifications.
Furthermore, Excimergrade Fused Silica, available in SQ0 or SQ1, offers exceptional transmission at 193 nm and 248 nm wavelengths, with the lowest levels of laser-induced fluorescence. This makes it particularly suitable for excimer laser applications, where precision and clarity are paramount. The versatility and precision of SQ Fused Silica make it a preferred choice for professionals seeking high-performance materials in advanced optical and photonic applications.
