Bk7 vs fused silica

WebFused Silica, SiO. 2. Glass Properties. Fused silica is a noncrystalline (glass) form of silicon dioxide (quartz, sand). Typical of glasses, it lacks long range order in its atomic structure. It’s highly cross linked three dimensional structure gives rise to it’s high use temperature and low thermal expansion coefficient. WebFigure 2-1: Measured optical constants of fused silica (SiO 2 glass). The influence of the UV-edge on the refractive index is clearly visible.
