Description
Discover the exceptional qualities of SQ Fused Silica, a superior material designed for the production of optical and photonic devices. This ultrapure fused silica is particularly valued in the fiber optic, semiconductor, and display technology markets, as well as for various optical and laser applications. Renowned for its inclusion- and bubble-free nature, SQ Fused Silica offers outstanding optical and physical properties, ensuring reliability and performance in demanding environments.
One of the standout attributes of SQ Fused Silica is its remarkable laser durability. It maintains refractive index homogeneity, ensuring consistent optical performance across various applications. The material also boasts impressive thermal stability and resistance to temperature shock, making it an ideal choice for environments subject to rapid temperature changes. Additionally, its low stress birefringence and small thermal expansion coefficients contribute to its stability and precision, essential for high-precision optical components.
The high OH and H2 content in SQ Fused Silica results in extremely low fluorescence, even under high-energy UV and laser radiation. This feature is crucial for applications requiring high stability and minimal interference from fluorescence, ensuring that the material performs optimally in critical optical systems.
LEONI offers SQ Fused Silica in a range of forms, including ingots and semifinished products such as round discs, rods, plates, and blocks. Available in five quality grades, these products are tailored to meet specific customer requirements. The quality grades are determined through rigorous measuring and selection processes to ensure that the material meets the highest standards for homogeneity and absence of striae.
The SQ0 grade is a 3D material free of striae, ideal for optical elements with multiple light directions, such as prisms and lenses. The SQ1 grade offers high homogeneity and is free of striae in the functional direction, suitable for lenses, discs, wafers, and rods. For technical applications, SQT grade is available, focusing less on homogeneity but still providing reliable performance. Furthermore, the Excimergrade Fused Silica, available as SQ1 or SQ0, offers excellent transmission at 193 nm and 248 nm, with the lowest levels of laser-induced fluorescence.
