Why use fused silica in optical components?
In optics, fused silica provides excellent UV transmission and can be manufactured to facilitate the transmission of infrared wavelengths. Coupled with low refractive index variation, it exhibits ideal optical qualities for high-precision optical applications. In addition, the physical properties of fused silica glass make it particularly suitable for high-performance applications in harsh conditions. Some of its most useful properties include: ▷ Extremely high hardness ▷ High-temperature resistance ▷ Broad optical transmission in the UV spectrum, but some IR fused silica glass can be used ▷ Extremely low permeability ▷ Low coefficient of thermal expansion (CTE) ▷ High chemical purity ▷ Excellent corrosion resistance ▷ Excellent electrical insulation properties ▷ The low refractive index change ▷ Low birefringence value ▷ Large size capability ▷ State-of-the-art homogenization level Internal Transmittance of high-quality JGS1 from China: Thermal properties Fused silica has excepti
