Fused Silica Wafers
Overview
Fused silica wafers are made from high-purity quartz glass and are known for their exceptional optical clarity, high temperature resistance, and low thermal expansion. These properties make fused silica wafers an ideal choice for applications requiring precise optical performance, thermal stability, and resistance to harsh environments. They are commonly used in semiconductor processing, photonics, and MEMS devices.
Product Features
Optical Clarity
Fused silica wafers offer extremely high transmission across a wide spectrum, from ultraviolet (UV) to infrared (IR), making them ideal for optical and photonic applications.
Thermal Stability
Capable of withstanding temperatures up to 1,000°C, fused silica wafers are highly resistant to thermal shock and deformation, ensuring reliability in high-temperature environments.
Low Thermal Expansion
Fused silica's ultra-low coefficient of thermal expansion ensures dimensional stability under temperature variations, minimizing the risk of cracking or warping.
Optical Transparency
Fused silica wafers are highly resistant to chemical corrosion, ensuring durability in semiconductor fabrication and harsh chemical processing environments.
