Custom Fused Silica Windows

Product Description

Fused silica is used in the ultraviolet to near-infrared spectrum. It has a good transmittance in the range of 220nm-2500nm. After double-sided coating, the transmittance of fused silica windows reaches 98%. Compared with H-K9L (N-BK7), fused silica has better uniformity and lower thermal expansion coefficient. Besides, fused silica has strong chemical stability and good thermal shock resistance. Fused silica windows are suitable in harsh environments and have a long service life. Fused silica windows are used for laser optics, optical measurement and so on.

Fused Silica Windows is stronger than N-BK7 windows, it have better homogeneity, lower coefficient of thermal expansion, it can be used at temperatures up to 1050°C. RZ Optics supplies Fused Silica Windows for a variety of UV ultraviolet, visible and Infrared transmission with high quality.
