Optical Fused Silica is amorphous, isotropic form of silicon dioxide (SiO2). The material has high homogenity and good transmission in the ultraviolet, visible and infrared spectral regions. Depending on transmission range there are UV and IR Optical Fused Silica (SiO2) grades: the useful range of UV grade is 0.17 - 2 µm and of IR grade is 0.23 - 3.5 µm. Optical Fused Silica (SiO2) is less dispersive than cultured quartz, does not suffer degradation when exposed to gamma or x-rays and has low coefficient of thermal expansion, what makes it highly resistant to thermal shock.
Products manufactured from Optical Fused Silica (SiO2): lenses, windows, wedges, optical beamsplitters, optical filters, prisms, etc.
