Fused Silica Window Examples

What are Fused Silica Windows?

Due to their exceptional optical properties and durability, fused silica windows are highly prized in technical and scientific applications. Made from synthetic amorphous silicon dioxide, these windows boast remarkable transparency across a wide spectral range, from ultraviolet (UV) to infrared (IR). They are particularly valued for their low thermal expansion coefficient, ensuring dimensional stability and thermal shock resistance under rapid temperature changes. Additionally, fused silica is chemically inert, making it resistant to most acids and other corrosive agents. This combination of features makes fused silica windows ideal for harsh environments where high optical clarity and physical reliability are paramount.
