Fused silica window characteristics
Dimensions D34x12mm with shouldered edge for tighter assembly.
Fused silica material
Material used for this part : CORNING HPFS (High Purity Fused Silica).
Available glass codes : 7980, 7979, 8655. Ideal for big dimensions fused silica parts.
Low birefringence (<5 nm/cm) and high transmission from UV-A to IR.
As for all fused silica materials, the thermal expansion coefficient are very low.
