fused quartz windows
Fused silica glass , also known as fused quartz glass , stands out as the optimal material choice for manufacturing optical windows that demand high precision and superior light transmission .
Exceptional Optical Performance
Offers high light transmittance , typically exceeding 94% across a broad spectrum, along with excellent optical homogeneity featuring minimal bubbles and striae . This minimizes light scattering, reflection, and absorption
Outstanding Thermal Stability
Features a very low coefficient of thermal expansion (CTE) , providing excellent resistance to thermal shock . It can withstand high temperatures up to 1200°C while maintaining high transmission rates
Durability and Reliability
Exhibits good chemical resistance and excellent surface quality , including high flatness and parallelism . These features ensure the protection and safety of sensitive optical systems and components
