Description
SQ Fused Silica – Especially for the production of optical and photonic devices in the fiber optic, semiconductor and display technology markets, as well as for optical applications and laser applications. The particularly inclusion- and bubble-free material features excellent optical and physical properties:
■ Laser durability
■ Refractive index homogeneity
■ Thermal stability and temperature shock resistance
■ Low stress birefringence
■ Small thermal expansion coefficients.
Due to the high OH and H2 content our fused silica SQ shows extremely low fluorescence and high stability under highenergy UV and laser radiation.

Frequently Asked Questions
SQ0 is a 3D material free of striae and striations in any functional direction and is recommended for requirements in optical elements with several light directions such as prisms and lenses. SQ1 has high homogeneity and is free of striae and striations in the functional direction, and is typically used for optical elements such as lenses, discs, wafers, and rods/fibers.
SQ Fused Silica is suitable for excimer laser optics and beam guiding systems, DUV and UV optics components, standard optics (VIS and NIR), UV rods, preforms and optical fibers, laser fusion, fused silica vessels and windows, lithography and microlithography applications such as stepper lenses, photo mask blanks, wafers, and lithography optics.
SQ Fused Silica is inclusion- and bubble-free and features excellent optical and physical properties such as laser durability, refractive index homogeneity, thermal stability and temperature shock resistance, low stress birefringence, and small thermal expansion coefficients.
SQ Fused Silica is available in five quality grades concerning homogeneity, absence of striae, and application type: SQ0, SQ1, SQT, SQ0-E193/SQ1-E193 (ArF excimer grade), and SQ0-E248/SQ1-E248 (KrF excimer grade).
SQ Fused Silica is used for the production of optical and photonic devices in the fiber optic, semiconductor, and display technology markets, as well as for optical and laser applications.
