Fused Silica Windows
Fused Silica Windows is based on UV-grade synthetic fused silica. UV Fused Silica window provides better performance from UV to IR spectrum than BK7 windows. Also, it is the best choice in terms of thermal stability.
In addition to superior transmission characteristics, synthetic fused silica exhibits higher thermal properties, exceptional purity, and excellent environmental durability for demanding applications.
