Description
SQ Fused Silica is a premium material designed for the production of optical and photonic devices, particularly within the fiber optic, semiconductor, and display technology markets. This material is renowned for its exceptional optical and physical properties, making it an ideal choice for applications requiring high performance and reliability. The material is meticulously crafted to be inclusion- and bubble-free, ensuring superior quality and performance across various optical applications.
One of the standout features of SQ Fused Silica is its remarkable laser durability. This property, combined with refractive index homogeneity and thermal stability, makes it suitable for environments that experience temperature fluctuations and thermal shocks. Additionally, the material exhibits low stress birefringence and small thermal expansion coefficients, which are critical for maintaining precision and accuracy in optical systems.
Thanks to its high OH and H2 content, SQ Fused Silica demonstrates extremely low fluorescence and exceptional stability under high-energy UV and laser radiation. This makes it particularly advantageous for applications involving excimer laser optics, DUV and UV optical components, and standard optics spanning the VIS and NIR spectrum. The material is also suitable for technical applications, including fused silica vessels and windows, as well as lithography and microlithography applications.
Design and Quality are at the forefront of LEONI's offerings, with SQ Fused Silica available in various forms such as ingots, round discs, rods, plates, and blocks. Customers can choose from five quality grades, each tailored to specific needs regarding homogeneity, absence of striae, and application type. These quality grades ensure that the fused silica can be effectively utilized in the optical application range from DUV to NIR, meeting the stringent demands of modern optical technology.
LEONI's commitment to quality and customization ensures that SQ Fused Silica can be precisely matched to customer-specific applications, providing a versatile and reliable solution for a wide range of optical and photonic challenges.
