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