Fused Silica is a superior optical material possesses excellent optical, chemical and physical properties with is formed by chemical combination of silicon and oxygen. Advantages of fused silica material include: good UV and IR transmission, stability
Fused Silica is a superior optical material possesses excellent optical, chemical and physical properties with is formed by chemical combination of silicon and oxygen. Advantages of fused silica material include: good UV and IR transmission, stability and resistance to thermal shock over large temperature excursions, low thermal expansion, wider thermal operating range and high laser damage threshold.
A-Star use the JGS1 material to equivalent the Fused Silica.
