Product Description
Amorphous Phase SiO2 Fused Quartz and Fused Silica Wafer with superior transmission in infrared and ultraviolet spectrum applications.
Material Properties
Fused Silica (Fused Quartz) is the amorphous phase of quartz (SiO2) with no additives, providing pure SiO2 composition. Compared to borosilicate glass, fused silica offers higher transmission in both infrared and ultraviolet spectrums.
