The FSW18 is an uncoated, 50.0 mm in diameter and 5.0 mm thick UV Fused Silica window with &lambda,/10 transmitted wavefront distortion. UV fused silica is the best choice to use in the ultraviolet region down to 195 nm due to its extraordinary high optical transmissivity for ultraviolet light. Fused silica is ideally used in high-energy laser applications with its high laser damage resistance. Its low thermal expansion coefficient allows the window to withstand very high operating temperatures, making this window an excellent choice for more demanding applications.
