Fused Silica Lenses

Fused Silica material has advantages over regular optical glasses. It is often used in deep UV or NIR systems due to its high transmission in those spectral regions. Due to the material’s inherently hard SiO2 amorphous structure and its exceptional chemical homogeneity, it displays high laser damage threshold and endures high operating temperatures. These lenses are often used in laser and imaging systems.
